Glass of water is what size ?

BlueBaron37

I been classing it as 250 ml, but the thought occurred to me I just made that up lol. Is there a measure for what a glass equals because I ain't seen it.

Sabine_Stroehm

I've been assuming 8oz, too. I think we're right.

dancingj2

8 ounces - one cup.

wranglerlaura

On the food portion of the website it says, " 8 cups of water a day". A cup of water is 8 ounces. That is the standard for most nutrition sites.

HMVOL7409

In technical terms a cup is 8 oz; so 64 oz a day.

ElizabethRoad

Where are you seeing anything about a glass? A glass could be any size. The water tracker says they recommend at least 8 cups of water a day. A cup is a standard measurement of 8 ounces, which is about 237 ml. Close enough to 250.

However you may also notice that the tracker itself is merely a picture of a drinking glass with a number on it. It does not actually say it represents a cup. You can use it for any measurement you want.

How funny. It does say cup. I guess because it's a glass, I'd been thinking it said glass.

per my nutritionist friend. DO NOT GO BY THAT ANCIENT RULE!!!!
Take your body weight in pounds. divide it by 2. thats how many FL OZ of water you should drink a day.

That's kind of logical. A 120 pounds girl won't need as many glasses of water than a 220 pound women..

ElizabethRoad

Actually you can just drink when you're thirsty, and if your pee is mostly clear you're good. But if you insist on tracking your water, the tool is there.

That doesn't make sense. Really, who can drink 110 fluid ounces of water a day, which is what a 220 pould woman would need to do.

I drink twice what they recommend. Any less and I feel dehydrated.

A cup is a standard measurement of 8 ounces, which is about 237 ml. Close enough to 250.

This is nitpicky but just to correct, a cup is not a standard unit of measurement, a cup means different things in different countries. In Canada and Australia, a cup is 250ml. In the US, a cup is half a pint. In Japan, a cup is 200ml.

It makes following recipes quite interesting!

This answer doesn't exactly represent what you asked :-) but I consider a glass as 8 ounces for purposes of entering into MFP. Everyone has an opinion on what you really should drink per day but ultimately you and your doctor are the only ones that can say what is best for your body. I drink when I'm thirsty and some days I'm thirstier than others and haven't had any problems drinking 8 cups per day. I can say that I won't follow what kimber_av said because there is no way I'm not going to drink 137 fl oz (2 gallons) of water every single day. Here's a link to an article by the Mayo Clinic that pretty closely matches the 8X8 rule (8 ounces X 8 per day)

http://www.mayoclinic.com/health/water/NU00283

The Institute of Medicine determined that an adequate intake (AI) for men is roughly 3 liters (about 13 cups) of total beverages a day. The AI for women is 2.2 liters (about 9 cups) of total beverages a day.

Generally if you drink enough fluid so that you rarely feel thirsty and produce 1.5 liters (6.3 cups) or more of colorless or light yellow urine a day, your fluid intake is probably adequate. If you're concerned about your fluid intake or have health issues, check with your doctor or a registered dietitian. He or she can help you determine the amount of water that's right for you.

i would need 18 .5 cups of water (148 oz) could you imagine those who are even higher weights
that is over kill .. i drink 60 oz a day plus 12 oz diet dr. pepper .. i couldn't possibly drink more

plus there is such a thing as water intoxication

so you want me to drink 13 glasses a day?? I can barely get to 4/5 :laugh: no chance in hell, unless I cut away every other fluid intake, which I don't see happening....ever.

mike_brooks

Your right. 1 glass of water is 8 fluid ounces.

smoffette

Actually, that does not make sense. Blood volume does not increase linearly with weight.

It's really not that hard, just use a larger glass.

I just figured it out that I drink about 64 oz of water a day. Half a gallon.

Actually it is a standard measurement. Just because different countries have different standards doesn't invalidate that. And one could assume that a US site would use the US standard. But thanks for your smart-alec reply, all the same.

runtrx

A cup of water is 8oz. 1oz = 30ml. So 240ml is 8oz.

Those that are questioning how I get 30ml per 1oz that is the guidelines we use at all the health facilities I have worked at as well as the guidelines for Nursing School.

i drink at least 120oz of water a day. i take medication that requires me to drink a lot of water. i drink all day including while i'm sleeping. i wake up with severe thirst at least three times a night. but i'm an extreme, i'm sure most people can get away with a lot less than that.

A lot of my customers are doing it. Water is very necessary, and it keeps you away from cravings.

kimber_av

well I'm sure every body is different. but I do know that the closer you drink to your 1/2 body weight rule.. the more weight you'll lose. because its been shown that 60% of the time you think you need a snack... you are actually thirsty.
so you lose more and then need less water.

Oh excuse us, lets all hail The US of A center of the world! Yes this may be a AMERICAN site so the standards are American, but there is a place called the rest of the world where other "cup" measurements exist, and there are INTERNATIONAL people using this ALL AMERICAN site who have different cup and measurement standards so it is good for us to know those differences, which is what this poster was pointing out.

Any size you want it to be.

If you're trying to do the 8 glasses of water a day thing... that refers to an 8 oz. or cup of water. Sometimes called 8x8. I've been collecting up information from multiple different posts about drinking water, especially the ones where people say they're having trouble drinking that much or don't like water. Incompletely edited version copied below.

+++++++++++++++++++++++++++++++++++++++++
*Water*

This topic has come up multiple times. Look at some of the previous posts for some great ideas. I've compiled some of them here for your convenience. This post has a summary of some of the key points followed by some suggestions related to each point.

First, quite telling yourself that you don't like water. Like any change in behavior, you can sabotage yourself by convincing yourself you can't do it or that it's going to be terribly hard.

Second water can taste different. Tap water in different places and from different sources is different. So, don't just assume you don't like any water.

Third, water tastes and feels different at various temperatures and in different containers.

Fourth, don't try to drink too much water at once. Your body handles it much better a little bit at a time.

Fifth, there are many no to low calorie flavors you can add to water.

Sixth, miscellaneous other topics.

And finally at the end, there is a list of other pages -- Web sites and previous postings.

Good luck!

========== 1 Attitude ==========
Why are you trying to drink more water? Your health? To help you eat less? To be more hydrated? To avoid drinking other higher caloric drinks or foods? Keep your motivation in mind.

Don't keep reinforcing the belief that you can't drink water or don't like it. There are many options. The ones that work for you will depend on your reasons and tastes. Stop telling yourself things like, "I hate water." or "Water tastes bad to me." Many tastes are acquired and can change. In the meantime, find things that are better for you and try to make the experience of drinking water enjoyable.

Depending on your reasons, the various suggestions below may work better or worse for you. For instance, if you're interested in weight loss, water is a "filler" that makes you feel less hungary without calories, and it would be important for you to use low or no calorie additives. But if hydration for exercise is your main motivation, drinks with electrolyte replacements may be more important to you. There is some research showing that drinks with sugar and salt will be better absorbed by the body than plain water.

Water isn't the only thing you can drink to stay hydrated or to fill-up. It is generally a healthy, inexpensive drink. But if you truly don't like it or the options below, there are other things you can drink.

========== 2 Different Water ==========
All water does not taste (or feel) the same. Water from different sources and treated in different ways will taste different. (Where I used to live, the tap water tasted fine at home, but not at my workplace. Same city supply system. Go figure! Different pipes?)

Try different waters. Tap, filtered, carbonated, different brands, etc.

Also, be aware that some bottled waters add salt. If you're exercising and trying to regain salt as well as water, that may be good, but for people watching their sodium or salt intake, check the label. (Sometimes the big advertising words say "minerals"... remember salts are minerals.) Some people find this easier to drink than "plain" water. Salt may help your body absorb water, but it can also be a problem for people with high blood pressure or other reasons to reduce their salt intake.
Dasani water (has salt)

There's the feeling and taste of water in your mouth, but also in your stomach. Some people report that very cold water makes their stomachs uncomfortable or even hurt. Obviously, that can be a disincentive to drinking more.

On the other hand, some people find that carbonated water helps settle their stomachs.

* distilled water
* filter your water
- where I grew up there was lots of iron in the soil, and so in the water. It had a horrible, metallic taste.
- some people are more sensitive to the taste of additives they put into drinking water to make it safe or protect your teeth, like fluoridation
- in some places, even the tap water is a bit salty
* try carbonated water
- there are many different kinds so check out a few, but be careful, some add sweeteners or salt (which can be good or bad depending on your situation)
- I started with carbonated, flavored water, but eventually got used to plain water and actually prefer it now. (See more suggestions for flavorings and brands in section 4 below.)
* water/fruit infusion pitcher

Remember that as you get used to different food (and drinks) and ways of eating your sense of what's good may change. I know that once I take some of the super-sweetened things out of my diet, I become more sensitive to the sweetness in other things. So give yourself a few days to get used to the change. Some people felt like they had to "force" themselves to drink more water initially, but then grew to desire it. Like any other habit it may be hard at first.

========== 3 Temperature and Container ==========
Many people who don't like water at room temperature are ok with it at a very cold or almost boiling temperature. In addition to the temperature, the container and convenience can make a difference.

I also find that cold water sometimes tastes better. For some people very cold, almost frozen water is best; others prefer hot water.

Some people with sensitive teeth, prefer drinks at room temperature.

And a container can help keep the water at the right temperature. The wrong glass or mug can make the water taste worse. Another thing... someone mentioned drinking water out of a container you like. That can be very important. Water out of a metal holder may taste metallic. Water out of a glass that still has some dishwasher detergent residue in it tastes awful! I prefer a clean, clear glass or a ceramic mug (sometimes chilled), but you may like something else. Try a few things and see.

Some people find water (or any drink) more palatable through a straw.

Bottled water in plastic, in the heat can pick up an odd taste, and possible some odd chemicals from the warmed plastic. (Snopes.com says that part of this is myth, but not all.)

Suck on ice.

* try different temperatures
- some water that I hate at room temperature is ok with ice or chilled
- or try heated (optional: with tea or other flavor)

========== 4 Amount and Speed ==========
I see a few people suggest "chugging" water. That can actually be dangerous and bad for you. Ok, probably for a glass or two, but not these folks who try to drink 32, 64 or more ounces at once. (More information in some of the references at the end.)

You're probably ok... just don't drink multiple glasses quickly. As someone else suggested, keep water handy and drink it a bit at a time throughout the day. In addition to the water intoxication or poisoning (see links below), you can stretch out your stomach. I know a woman who got an infection due to the regular stretching and then folding of her stomach when she was drinking about 32 oz each night to "catch up" on what she was supposed to eat during the day.

Like anything... food, sleep, exercise, the key is finding the right balance for your body instead of doing crazy-extreme things. As the articles below suggest, part of the problem with too much water can be the watering down of other necessary nutrients or electrolytes. As with all health information, consider the source and be careful.

Try to keep a glass or bottle of water nearby and sip it occasionally throughout the day.

Also, keep a shot glass in kitchen, every time you go by, take a shot. Gets it down without having to face the whole glass.

* try smaller quantities at a time
- just sitting (or better standing) there drinking water is not many people's idea of a good time, but...
- keep a bottle or glass of water by you and sip it while you're doing other things, and you may not notice the taste as much

========== 5 Adding Flavors ==========
A little lemon or lime juice can make water much more palatable for people who don't like plain water without adding many calories.

Try no or low cal flavorings:
- if you don't like lemon, do you like other citrus (I prefer lime.)
- or do you like mint? A bit of crushed mint can add a nice flavor.
- stem of rosemary (soak for awhile), sprig of mint
- sliced fresh ginger (soak in water overnight)
- frozen or crushed fruit
> orango, lemon, lime - slices or squeezed juice
> strawberries, watermelon, blackberries
> mint leaves
> cranberries
> frozen raspberries or cranberries
> crushed plums or cherries
- cold water with cucumber slices
- a tiny (and i mean tiny) bit of no added sugar cordial
- almond extract

Teas and coffees:
Depending on the type and quality of the tea or coffee, different amount of sweeteners may be added. Some people will prefer it with milk or cream, that adds calories. Caffeine varies by the different kinds, and whether caffeine is a problematic ingredient will depend on your motivation for drinking water.

Licorice tea - Stash makes a nice licorice spice caffeine free herbal tea. Licorice is a natural sweetener, so the tea needs no sugar. It's very sweet.
Caveats: I have no association with Stash except as a happy customer. Stash warns that, "Licorice root is not intended for use during pregnancy and while nursing, or if you have heart disease or high blood pressure."

Herbal teas, several people recommended hibiscus tea
Black, green and white teas all have varying amount of caffeine, and caffeine is a diarrhetic, so it dehydrates you off-setting the value of the water. (Keep your goal in mind. Are you trying to be more hydrated for exercise, to fill yourself up, so you eat less, or something else? The importance of dehydrating side effects will depend on the reasons you're trying to drink more water. You still get some hydration from caffeinated beverages, but not as much as from something that isn't caffeinated. Experts disagree on the amount of off-set.)

Honey's nice, but it adds some calories too. It's especially good in hot water. Add citrus (lemon or lime), if you like.

Artificial flavors
I don't like artificial sweeteners or flavors. They give some people a bad after-taste, headache or other side-effects, but if you're ok with them…
Crystal Light
Smart Water.
Archer Farms natural drink mix packets ?
MIO
Propel
Fiji, Smartwater, and Pellgrino (carbonated)
Sobe Lifewater 0-But does have minimal salt & carbs
Green tea
Hawaiian Punch packets
"Polar Blast"
Torani Sugar-Free Raspberry, Black Cherry, Lime, or Orange syrups
Slim Quick stuff
Lifewater or Vitamin Water Zero. They taste great!
Also I drink water over ice with fresh lemon and sweet n low
Diet Peach Tea Snapple
diet sodas (some people think that a sweet taste will kick up insulin production and cause more hunger)

Flavored carbonated water
* Italian sparkling water - flavored,
* flavored seltzer
Some brands that people have recommended:
Try True Lemon products. They are sugar and artificial sweetener free and they have lemon, lime, orange and other flavors.
You could also try sparkling water, my favorite is La Croix. They have lemon, lime, berry, grapefruit and a couple more I think.
I started with the Cap [Cap10] carbonated, flavored water, but eventually got used to plain water and actually prefer it now.
a water called HINT

Other drinks (may have more calories)
Gatorade or Powerade
Emergen-C - has a variety of flavors, adds about 25 calories per packet, but also adds vitamins and minerals, can be used to flavor cold or warm water
coconut water (not coconut milk, but the water of fresh, green young coconuts) 46 calories per 8 ounces, is high in potassium, but also very high in sodium for a fruit juice--280mg/8 ounces! Naked brand coconut water in carton tastes good but more expensive than Vitacoco and O.N.E.in carton.



========== 6 Miscellaneous ==========

Juice and liquid in foods (stew, smoothies, etc.) help keep your body hydrated too. (See references and links regarding the 8 8oz. glasses of water myth below.) Water is not the only way to stay hydrated. But, dehydration is dangerous. Among other things, it can contribute to gallstone problems.
In addition, if you're not used to exercising as much as you do now as you work towards becoming more fit, you may not have gotten into the habit or even realized that when you loose more water as you exercise, you need to imbibe more water. Another situation where this can be important is for those on high protein diets that tend to make your kidneys work harder.

Alcoholic beverages have two liquid solvents -- water and alcohol. So, they still contribute to your hydration, but not as much as other things you can drink. Alcoholic beverages are also high in calories, usually low in nutritional content and can even increase the need for some vitamins.

A cup is a standard measurement of 8 ounces, which is about 237 ml. Close enough to 250.

This is nitpicky but just to correct, a cup is not a standard unit of measurement, a cup means different things in different countries. In Canada and Australia, a cup is 250ml. In the US, a cup is half a pint. In Japan, a cup is 200ml.

It makes following recipes quite interesting!

Actually it is a standard measurement. Just because different countries have different standards doesn't invalidate that. And one could assume that a US site would use the US standard. But thanks for your smart-alec reply, all the same.

I think the first poster meant it's not an international standardised unit, which is a fair point and not at all smart-alecy. Incidentally, in the UK we go by 'a glass of water' - no measurement given. Just because us locals know what that means doesn't mean that perhaps it couldn't be labelled clearer.

tinkermommc

per my nutritionist friend. DO NOT GO BY THAT ANCIENT RULE!!!!
Take your body weight in pounds. divide it by 2. thats how many FL OZ of water you should drink a day.

That's kind of logical. A 120 pounds girl won't need as many glasses of water than a 220 pound women..

That doesn't make sense. Really, who can drink 110 fluid ounces of water a day, which is what a 220 pould woman would need to do.

LOL! I think I'd drown!! Which can really be done if you drink excessive amounts of water. Well not drown but hyponatremia, low sodium, which is also bad.


I typically drink 4, 16 oz glasses :-)

Here's what Mayo clinic has to say...http://www.mayoclinic.com/health/water/NU00283
