How it works
Cups measure volume, recipes need mass, and the bridge between them is density — which is why this converter asks which ingredient you are measuring. A cup of flour and a cup of sugar occupy the same space and weigh very differently. Rough figures for a 240 ml cup: flour about 125 g, granulated sugar 200 g, butter 227 g, water 240 g. That flour-to-sugar gap of 75 g in a single cup is enough to change a cake, which is why baking recipes written by weight are more reliable than those written by volume. Flour is the worst offender because it compresses. Scooping the cup straight from the bag packs it and can add 20% over spooning it in and levelling off. Serious bakers weigh their ingredients for exactly this reason — a kitchen scale removes the entire source of error.

Frequently asked questions
How many grams in a cup of flour?
About 125 g for all-purpose flour (1 US cup = 240 mL).
Why does it ask for the ingredient?
Because cups measure volume, not weight — and each ingredient has a different density, so 1 cup of sugar ≠ 1 cup of flour in grams.
Is an American cup the same as a European one?
No. A US cup is about 240 ml, a metric cup 250 ml, and an old imperial cup 284 ml. On a recipe from another country, check which is meant — a 4% difference compounds across several ingredients.
