Why milk needs its own conversion
Milk weighs about 245g per cup — denser than flour or sugar, closer to how liquids like milk measure. Whole milk; low-fat/skim vary only slightly. A cup is a unit of volume, so ingredients this different in density can't share one generic conversion factor — using a single "1 cup = X g" rule for everything will be wrong for at least some of what you cook.
Common measurement mistakes
- Using a generic cup-to-gram factor for every ingredient — milk does not weigh the same per cup as most other ingredients.
- Measurement note: Whole milk; low-fat/skim vary only slightly.
- Confusing weight ounces with fluid ounces when a recipe lists "oz" — they are not interchangeable.
Frequently asked questions
How many grams are in a cup of milk?
About 245g, whole milk; low-fat/skim vary only slightly.
Does this conversion work for every brand or variety of milk?
It’s a close approximation based on USDA (placeholder). Minor variations in moisture, grain, or brand can shift the exact weight slightly, but this figure works well for everyday cooking and baking.
