About the Cups to Grams Converter

There is no single answer to how many grams are in a cup, because a cup measures volume and a gram measures weight. A cup of all-purpose flour weighs about 125 grams, a cup of sugar about 200, a cup of butter 227 and a cup of honey 340 — which is why a baker who weighs gets the same cake every time.

Pick the ingredient, type the number of cups — fractions such as 2/3 or 1 1/2 are fine — and choose the cup size: US, metric or UK imperial. The converter gives the weight in grams and ounces and lays out the common measures from an eighth of a cup to four cups, plus a teaspoon and tablespoon. Tick grams to cups to go the other way.
