A bag of rice that has 500g of rice provides, for example, 4 servings of 125g. If I use 1/4 of the bag I can do so fairly reliably with the eye (like the person who uses the size of her hand) and accept the standard deviation, which I do. However I still need useable data about the content of 125g or rice. The answer to…

...em that's 4 measuring cups? You're right I'm not from the US.

Fair point. I imagine, for commercial reasons, that attempts are made not to be overweight. But items do change weight through dehydration so if the weighing is done and point A in the food chain it may shift weight by point B so some tolerance of standard deviation has to be allowed for.
-
I take the point but presumably you have reliable measurement. Someone earlier in the thread indicated that a cup does have a universally accepted measurement in milliliters which is really helpful. Aside from that it seems(a) subjective and (b) a unit of volume not weight which cannot be easily translated
-
Fine but to turn volume into weight requires information about mass which is not readily available
-
It doesn't matter. If half are off by 20% in one direction and half are off by 20% in the other direction then the total is accurate. That's just standard deviation. The same is true about nutrition content. There is a significant amount of error in the food nutrition composition but the errors cancel each other out…

Nope. Most food packaging shows the weight of the food. Some packaging also shows the nutrition per 100g but thattends to be processed food which I try not to eat for obvious reasons.
-
Nope. On average the errors cancel each other out statistically. So, I may buy a piece of fish and the package says 138g (Just by way of example). It may be inaccurate but on average the errors will cancel themselves out (some will be under and some over but the law of large numbers mean that over time the data will be an…

Food packaging shows weight in most cases.

So a cup of rice, tells me the volume not the weight but food calories are a weight-based measurement. If Americans don't usethe metric system, use Ounces and Pounds which at least can be meaningfully converted. Sure I could use a food scale, and sometimes I do, but usually I am measuring against something that the store…

IMHO the site should regulate the available measuring systems so that the information on the site is meaningful. How big is the measuring cup? Does a cup of x weigh the same as a cup of y? And so on. Sometimes there seem to be 10 of these nonsense "cup" entries for 1 usable entry. What's the point of sharing information…
