Milk (Whole):
Grams to Cups
By Stefan Ulrich · Last updated
Whole milk weighs 244 grams per cup — just barely heavier than water (240 g/cup). All milk types, from skim to full-fat, fall within a tight 240–248 g/cup range, making milk one of the most predictable ingredients to convert between cups and grams.

About Milk (Whole)
Skim milk is almost pure water by density: 242 g/cup. Whole milk (3.25% fat) adds a negligible 2–4 grams. Heavy cream, by contrast, is noticeably lighter at 238 g/cup because fat is less dense than water — a counterintuitive fact.
Plant-based milks vary slightly more. Oat milk runs about 245 g/cup. Almond milk is lighter at approximately 240 g/cup due to its lower protein and fat content. Coconut milk (the carton variety, not canned) is about 240 g/cup. Canned full-fat coconut milk is much denser: approximately 270 g/cup.
For baking, the choice between milk types matters more for flavor and fat content than for measurement accuracy. A recipe calling for 1 cup milk works with any type at the same volume. The notable exception is buttermilk, which weighs 245 g/cup and adds acidity that interacts with leavening — substituting regular milk for buttermilk requires adding 1 tablespoon vinegar or lemon juice per cup.
Evaporated milk (canned, concentrated) is significantly denser at about 252 g/cup. Sweetened condensed milk is heavier still at approximately 306 g/cup due to its high sugar content.
Tips for measuring Milk (Whole)
- All fresh milk types: ~240–245 g/cup. The fat percentage barely affects weight.
- Buttermilk substitute: 1 cup milk + 1 tbsp white vinegar, let sit 5 minutes.
- Canned coconut milk: ~270 g/cup — much denser than carton coconut milk.
- Sweetened condensed milk: ~306 g/cup — very different from regular milk.
- Milk density changes with temperature, so warm or cold milk can shift the gram result slightly.
- For baking, use the milk called for in the recipe; whole milk behaves differently from skim in texture.
- Whole milk and skim milk have almost the same weight per cup, but the fat level changes how rich the result feels.
Common mistakes
- Substituting canned coconut milk for carton coconut milk — density is very different
- Using regular milk when buttermilk is called for without adding acid
- Assuming 1 cup of milk always equals exactly 240 g in every kitchen
- Using very hot milk in a batter that needs gentle incorporation
- Substituting milk types without thinking about fat content changes the final crumb and browning.
