Grams to Cups Converter
It depends on the ingredient: 100 g of flour is about 0.8 cup, 100 g of sugar 0.5 cup and 100 g of butter 0.441 cup.
Grams measure weight and cups measure volume, so there is no single grams-to-cups number. A cup of all-purpose flour weighs about 125 g, a cup of sugar 200 g and a cup of butter 227 g. Pick the ingredient in the calculator or use the charts below.

Grams to cups
Weight and volume are different measurements. Select the ingredient for a practical density-based estimate.
1 lb all-purpose flour ≈ 3.63 cups
Estimates use the selected ingredient’s grams-per-US-cup density. Always follow your recipe’s measuring method.

What about milligrams?
Milligrams are too small for cooking by the cup: a cup of water weighs about 237,000 mg. Milligrams are used for nutrients and medicine, not for measuring ingredients.
Weights and volumes on this page use these grams-per-US-cup densities: all-purpose flour 125 g; whole wheat flour 120 g; granulated sugar 200 g; brown sugar 220 g; powdered sugar 120 g; butter 227 g; water 237 g; milk 244 g; honey 340 g; rolled oats 90 g; white rice 185 g; almonds 142 g. Packing, sifting and brand can shift real results by 5–15%, so weigh when a recipe depends on precision.
