100 Grams to Cups
100 grams is ⅞ cup of all-purpose flour, ½ cup of granulated sugar, or ½ cup 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.
100 g is also 3.5 oz by weight. For water and thin liquids, 100 g is simply 100 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.
Convert another amount
250 g All-purpose flour = 2 ⅛ cups
Exactly 2.08 cups — or measure 2 cups + 1 tbsp.
