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.
