How to Measure Milk
Measure liquids in a liquid measuring cup (Pyrex-style) at eye level on a flat surface.
For the most consistent results, use a kitchen scale. A cup measurement can vary by 15–30% depending on technique. Weighing eliminates that variable entirely.
Why the Gram Weight Varies by Ingredient
A cup is a measure of volume — how much space something occupies. Milk has a specific density (mass per unit volume) that determines how many grams fit in that space. The 240 g/cup value above is calibrated for the measuring method described (spoon and level where applicable).
Different ingredients have very different densities. Compare: water (237 g/cup), honey (340 g/cup), cake flour (96 g/cup). Using a single generic "cups to grams" ratio doesn't work — the ingredient must be specified.
