Divide the gram amount by 227 to calculate US cups. The practical fraction is a measuring aid, not a replacement for the exact gram weight.

Place a clear liquid measuring cup on a level surface and read the meniscus at eye level. If a recipe provides milk in grams, weighing it directly into the bowl is quick and avoids another cup.
Grams = cups × 227
One cup is 227 grams, one-half cup is about 114 grams and one-quarter cup is about 57 grams.
Common uses
- Cakes and pancakes
- Custards and sauces
- Bread dough
Milk is close to water but not identical. Whole, low-fat and skim milk have slightly different densities. Use the original recipe weight when precision matters and treat the cup result as practical guidance.
The converter does not assume that every cup weighs 237 or 250 grams. It uses the documented value for the exact ingredient and state selected.
If a product label or recipe publisher supplies a different gram weight for one cup, follow that recipe-specific value for the closest match to the original testing.
