Cup & Gram

425 Grams to Cups

425 grams is 3 ½ cups of all-purpose flour, 2 ⅛ cups of granulated sugar, or 1 ⅞ cups of butter — grams measure weight, cups measure volume, so the answer always depends on the ingredient's density. Find yours in the table below; every density is verified against King Arthur and USDA data.

425 g is also 15 oz by weight. For water and thin liquids, 425 g is simply 425 ml.

Why the ingredient changes the answer

A US cup is a fixed volume (about 237 ml), but a cup of flour weighs 120 g while a cup of honey weighs 340 g — density is the whole game. That's also why there's no single "grams to cups" conversion factor, and why our converter asks for the ingredient first.

Exactly 2.08 cups — or measure 2 cups + 1 tbsp.
