How to measure milk

Milk is very close to water in weight — one cup is about 240 grams. Whole, skim and low-fat all weigh within a gram or two of that.

Because a cup measures volume rather than weight, the most reliable way to measure milk is with a digital kitchen scale. If you are working from cups, keep your technique consistent every time so your results are repeatable. For more, see our guide on baking by weight versus volume.

Substitutes for milk

1 cup whole milk = 1 cup unsweetened soy milk (King Arthur Baking)
Soy matches whole milk's viscosity and protein best; closest performance in baked goods.
1 cup whole milk = 1 cup water + ¼ cup dried whole milk powder (King Arthur Baking)
Add powder to dry ingredients, water to wet. Useful for bread doughs.

Milk conversions: FAQ

Why doesn't a cup of milk weigh the same as a cup of water?

A cup measures volume, not weight. Milk is denser than water (240 g versus 237 g per cup), so the same volume has a different weight. Weighing in grams is the most accurate way to measure it.
