Cups to Grams Converter

It depends entirely on what is in the cup. A US cup is 236.6 ml, so a cup of water is 237 g, but a cup of all-purpose flour is about 120 g, granulated sugar 200 g, packed brown sugar 220 g, butter 227 g, honey 340 g and rolled oats 90 g. Pick the ingredient above for the right figure.

About 120 g for all-purpose flour spooned into the cup and levelled — the method most US recipe developers assume. Scooping the cup directly into the bag packs 140–150 g. Bread flour is 127 g, cake flour 114 g and whole wheat 130 g per cup.

Half a cup of granulated sugar is 100 g; half a cup of butter is 113 g (one US stick). A quarter cup of sugar is 50 g and of butter 57 g. The quick-reference table under the converter lists these fractions.

No. A metric cup (UK, Australia, NZ, Canada in modern recipes) is 250 ml, about 6 % more than the US 237 ml cup. For metric-cup recipes multiply the results here by 1.06 — or better, use the grams the recipe gives.

Because weight is exact and volume is not: two cooks can fill the same cup with 110 g or 150 g of flour. Most European and professional recipes work in grams; a kitchen scale costing a few dollars removes the guesswork, which is why converting a cup recipe to grams once and writing it down is worth doing.
