"1 cup" is a volume, but ingredients have different densities, so a cup of flour weighs about half as much as a cup of sugar. Here are typical weights for one US cup (≈ 240 ml). Different sources vary by a few grams depending on how the cup is filled.

Why weighing is better
Scooping flour directly with the cup can pack in 150 g or more, about 25% extra, which makes cakes dry and cookies thick. A kitchen scale removes that guesswork, and scaling recipes becomes simple multiplication. See how to scale a recipe.
If you must use cups
- Flour: spoon it into the cup, then level with a knife.
- Brown sugar: pack it firmly.
- Sticky ingredients: lightly oil the cup.
- Liquids: use a clear measuring jug at eye level.

Older handwritten recipes may use "teacups" or "tumblers". Cook the recipe once, note what worked, and update the recipe. See how to digitize family recipes.
