Am I being a stooge here? (Food scale question)

Ok so as a disclaimer I am not a noob, but I'm still having trouble figuring this one out....
I just bought ProYo Dark Chocolate Toffee ice cream for the first time (which was amazing BTW).
Heres my problem, the container says its 14 oz total (serving size is 81grams, 3.5 servings per container). So since I decided to eat half the container, I began to weigh out 7oz, that sounds logical of course... But that only left 2oz remaining in the container, not another 7oz!
SO I'm wondering if the calorie count by weighing out 1 serving is even correct?? If the whole container is 120cals x 3.5 servings, that makes 420 cals. But if you aren't actually spreading that out between a true 14oz, than it is actually more calorie dense then advertised.
A serving is 81grams, 3.5 per container (which equals 283.5 grams). But 283 grams is only 9.98 oz (Not 14). SO are they false advertising on the label here or what? Tell me i'm not crazy lol

A serving size is 81 grams. You need to weigh out 81 grams for a serving. 14 ounces is the volume (the space it fills), not the weight.10

Oz can be weight or volume. Take s measuring cup and see if it is 14 oz by volume.1

That's what I was thinking in the back of my head, but wasn't sure. Guess that can be confusing for some who look at the front of the package to get the total weight, not knowing that it was volume on the front package, scale weight on the back label. Thanks for clearing it up for me

Always grams. Because ounces are confusing, for reals

Icecream has larger volume per less weight w.r.t. water. I.e. it is less dense than water. Oz is a measure of volume. Only for water 1oz can be interpreted as weight.
In metric units (since imperial make no sense to me) 100gr of icecream has more calories than 100ml. Some brands in the UK/Europe give calories per 100ml and some per 100gr and some per both.
In your case oz should be interpreted as volume. The scale set to oz works for water only.2 -

Ok now Im getting all technical in my head here.. So when I measure milk, I usually use my scale on the ounces measurement. Is it better to go by ml's in that circumstance? Now I'm thinking I should read Food measuring for Dummies or something, I thought I knew what I was doing all these years!

The packaging clearly says 14 fl. oz.
fl. oz. = fluid ounce, which is a unit for measuring volume. No reason to be confused.2 -

I don't weigh liquids, I've always heard a scale will only really work for water. I use measuring cup/spoon for liquids. I weigh solids and semi-solids (like butters, mayo, jelly, sauce etc that lists grams on the package)0 -

Totally unrelated to OP, but yes you can weigh liquids for certain recipes. I make soap and lotion etc from scratch and for that you HAVE to weigh your liquids for accuracy.
So for food I'll measure out a volume amount of milk to drink for accuracy when calorie counting.
But if I'm making say, goat milk soap from scratch I will WEIGH out the goat milk for accuracy because that's what's needed to ensure accuracy from batch to batch. Also to ensure accuracy of your ingredient ratios so the the products come out right.
But yes, the only liquid that translates weight to volume, ounce per ounce is water.0 -

Scales cannot measure volume (milliliters are a measure of volume). When a scale purports to provide a volume measurement, it's converting weight to volume based on a relationship that is true for water at a specific temperature and pressure, or for other liquids that have the same specific gravity. For the purposes of calories, the formula will give a you a close-enough estimate for watery liquids.
But if you really want to measure volume, use a tool designed for that purpose, like a measuring cup or tablespoons.2 -

That sounds like a good strategy. I honestly usually weigh my milk, alcohol etc with the scale because I'm too lazy and don't want to wash more measuring cups.. This chef is like me I guess https://www.chefsteps.com/activities/weight-vs-volume-speed
I suppose if the slight calorie differences get in the way of my results I'll have to change my ways 1 -

Despite what your scale's setting may imply, you can't really weigh something to determine ml or fluid ounces (since those are volume measures, not weight measures), any more than you could weigh something to determine inches or centimeters.
For water ( ) or things of identical density, it'll be a close approximation, but not for other liquids. For better accuracy, you can do one of 3 things:
- Measure liquids with a measuring cup (for best accuracy, use one designed for liquids)
- Find an accurate estimate of calories per gram of a particular liquid, and use that (there are a few in the MFP database, or you can research & add your own)
- Find a conversion factor for your liquid to use as a multiplier (this adjusts for the difference in density between your liquid and water). IMO, this option is way too much trouble.
Personally, I only worry about accuracy for reasonably calorie-dense liquids (oil, milk, alcohol, etc.), not for things like (say) vinegar.0 -

Or you could use a database entry for milk in grams, not a database entry for milk in a unit of volume. Then you could go on using the scale and not have to wash measuring cups.
Plug this into the search field on MFP and you'll get an entry that lets you choose 100 g as the serving size:
Milk, nonfat, fluid, with added vitamin A and vitamin D (fat free or skim)
There are similar entries for low fat, reduced fat, and whole milk.3
