Hi

Please can some of you point out what in grams would a cup of something measure?

For example I'm getting figures for lentils but in a cup size as opposed to grams

Thanks

    A cup is a measure of volume where as a gram is a measure of weight...its apples and oranges you cannot give an answer to this question. Cups of different things will weight different amounts based on their density.

    One cup of water is about 236 ml and at a density of about 1g per ml its about 236 grams...but thats water. Something else would have a different density and a different weight.

    Asking how many grams are in a cup is like asking how many millimeters are in an hour.

    You need to weigh things. Cups are not accurate measurements for non liquids any figure someone gives you won't be accurate. Invest in some scales

    The first two entries that came up were one raw and one cooked. Both said 1 C as default, but if you click on it, a drop down menu comes up and you can choose the grams option on both of them. Sometimes you have to search for a while, but when you find an entry, click on the "size" measurement until you find one that also lists grams.

    You cannot compare weight to volume since they are completely different things. A cup of flour weighs a drastically different amount than a cup of quarters, for example. If you're having trouble tracking it on here, just enter the food in as grams per the "customize" button.

    Is this real life?

    Do you think a cup of steel and a cup of feathers weigh the same?

    ETA: Changed my answer from the original one I had.

    I think that is what the OP is asking, he is looking to measure it in grams not cups. To the OP most of the things that come in packages usually give both. Most scales have where you can measure in both grams and oz. I know mine does.

    Yes, they may be weight vs volume, but one cup of flour is always going to give you about 125 g of flour and a cup of lentils is going to be about 200 g of lentils. Sometimes, using a cup is more convenient than getting the scales out, or maybe the recipe calls for cups, and he only has scales...

    To the OP's question:

    It depends on the density of the thing being measured. For example, 1 cup of *dry*, whole lentils has a known density, and therefore a known mass in grams--approximately 200 g.

    http://www.cookitsimply.com/measurements/cups/lentils-dry-all-0070-014i0.html

    If the lentils are cooked, or if you're talking about densely packed lentil flour, or a cup of coffee beans instead, the density is different, and therefore the mass (in grams) will be too.

    I don't disagree with that but still impossible to answer OPs "how many grams in a cup" question.

    But who eats quarters??

    Google "cup to gram conversions" and try the first result you get, we are not supposed to promote websites on here so I can't give you the url, but it is a recipe site.

    It is not an exact science because cups is volume and grams is weight, but these tables help if you are really stuck.

    also depends on the measuring cup as:
    a US cup *should* be (by definition) 8 fluid ounces/ 16 TB/ 1/2 a US pint which is approximately 236ml
    whereas a CA/AU cup is defined as 225ml


    so a significant problem when picking one cup from the database is the country of the user that entered it, and this data is generally not available

    Don't know where 225 mL came from. There are lots of different "cups" though:
    According to Wikipedia:
    Metric cup is 250 mL. Used in Canada/UK/Australia etc. Note: not actually part of the Metric System, in spite of the name.
    US Customary cup is ~236.59 mL.
    US "legal" cup is 240 mL. Used for nutritional labeling purposes. ('Cuz math is hard?)
    Imperial cup is 284 mL.
    Japanese cup is 200 mL.
    Japanese Go "traditional cup" is ~180 mL. Used for measuring rice or sake.

    Don't even get me started on "cups" of coffee or Australian tablespoons!

    Moral of the story:
    If you're counting calories, protein, fat, carbs or whatever.. It's always best to find and use nutritional information in grams, and weigh your food!

    ^^ most def. You could take a cup (the very same measuring cup, not a canadian and an american one lol) of chex cerial and weight it, get a certain amount, then take another cup and get a slightly different amount.

    flour and sugar it would be less likely or not happen because there are tiny grains, but other things the oreintation/shape of the substance can slightly change how much is actually in the cup

    Some kind of cup is 237 ml. If you fill it with water, the water will weigh 237 g, whereas the measuring cup will weigh however much it weighs.

    I'll start with European/US tablespoons; 15 ml. Teaspoons are 5 ml. If they are filled with water, the weight is 15 g and 5 g respectively, but I don't think OP will consider this last bit very helpful.
