Measurement notes
- Milk is a liquid, so it should be measured in a liquid measuring cup at eye level for accuracy.
- Whole, low-fat, and skim milk have nearly identical densities, so the gram weight barely changes between them.
- Temperature has a small effect on milk's density — cold milk is marginally denser than milk at room temperature.

Measuring step this site recommends: poured, liquid measuring cup.
When sources disagree, follow your recipe: use its gram weights if it gives them, or measure the way its author did. The adopted value is one stated convention, not a correction of the other sources.
A comparable source-cup value only scales a half-cup or tablespoon serving to one source cup. When a source does not state the cup's exact volume, we do not present it as a fixed-milliliter normalization.
