1 cup in grams: King Arthur and USDA

Two trusted sources, side by side. King Arthur Baking publishes the weights its test kitchen bakes with; USDA's are laboratory measurements. They differ by a few grams because a cup can be filled more or less firmly. Either works; for a recipe, use the source it was written with.

All-purpose flour	120 g	125 g
Bread flour	120 g	137 g
Whole wheat flour	113 g	120 g
Almond flour	96 g	95 g
Cornstarch	28 g per ¼ cup	128 g

How to convert cups to grams

A cup of a light, airy ingredient (flour, cocoa, oats) weighs much less than the same cup of a dense one (sugar, honey, butter), so the conversion needs the ingredient's weight per volume:

grams = cups × grams per cup

Example: all-purpose flour weighs 125 g per cup, so 2 cups is 2 × 125 = 250 g. The weights come from USDA FoodData Central; each ingredient page links to its USDA record.

Water is the reference: 1 ml weighs about 1 g, so a 236.6 ml US cup of water is about 236.6 g (USDA weighs it at 237 g). An ingredient less dense than water (flour, oats, cocoa) weighs less than that per cup, a denser one (sugar, honey, salt) more. A metric (250 ml) cup holds about 5.7% more of everything. For cups to millilitres, see cups to ml.

Frequently asked questions

How many grams are in a cup?

It depends on the ingredient, because a cup measures volume (236.6 ml in the US). A cup of water weighs about 237 g, since 1 ml of water weighs about 1 g. Lighter ingredients weigh less: all-purpose flour 125 g, rolled oats 81 g. Denser ones weigh more: granulated sugar 200 g, honey 339 g.

How many grams in a cup of flour?

All-purpose flour: 120 g by King Arthur's chart, 125 g by USDA. Flour spooned into the cup and levelled is near the lower figure; scooped from the bag it is near the higher one. Bread flour is 120–137 g a cup.

How many grams in a cup of sugar?

Granulated sugar: 198 g (King Arthur) or 200 g (USDA). Packed brown sugar is 213–220 g; unsifted powdered sugar 113–120 g.

How many grams is 1 cup of butter?

227 g (USDA). Half a cup, one US stick or 8 tablespoons, is 113 g in both King Arthur's chart and USDA's.

How many grams is 1 cup of water or milk?

Water: about 237 g (USDA), because a US cup holds 236.6 ml and 1 ml of water weighs about 1 g. Whole milk is slightly denser: 244 g (USDA). King Arthur rounds both to 8 oz, 227 g.

Does a metric cup weigh more?

Yes, about 5.7% more, because it holds 250 ml instead of 236.6 ml. A metric cup of all-purpose flour is 132 g and of granulated sugar 211 g. Switch the converter above to "metric" for these.
