Cups to Grams Calculator
A cup of flour and a cup of sugar do not weigh the same, so converting cups to grams depends on the ingredient. Choose one, enter an amount in cups, tablespoons or teaspoons, and get the weight in grams and ounces — or switch direction to turn grams into cups.

Grams per US cup used here
All-purpose flour 120 g. Granulated sugar 200 g. Brown sugar, packed, 220 g. Powdered sugar 120 g. Butter 227 g (two US sticks). Milk 244 g. Water 237 g. Vegetable or olive oil 218 g. Honey 339 g. Uncooked white rice 185 g. Rolled oats 80 g. Unsweetened cocoa powder 85 g. Table salt 292 g.
These are averages drawn from standard food-composition tables and baking references. Real ingredients vary with brand, humidity, grind and above all how the cup is filled, so treat the result as a close estimate.
Why flour is the tricky one
The 120 g figure assumes flour that is spooned into the cup and leveled off. Scooping the cup straight into the bag packs it down and can give 140–150 g — up to a quarter more flour than the recipe intended, which is a common cause of dry, dense baking. Some references use 125 g per cup. If a recipe gives weights, use them.
Which cup?
This calculator uses the US customary cup of 236.6 mL. A metric cup, used in Australia, New Zealand and Canada, is 250 mL — about 6% bigger. Older British recipes may mean an imperial cup of 284 mL. For a metric cup, multiply the gram figure by 1.057.
