Cups to grams converter
Pick the ingredient and the amount, and get the weight in grams, because a cup of flour and a cup of sugar do not weigh the same.
Weights come from USDA FoodData Central household measures. A US cup is 236.6 ml; a metric cup is 250 ml. Nothing you enter is stored or sent anywhere. How we verify our data →
Cups to grams FAQs
How many grams is one cup?
It depends on what is in it. A US cup of water is 237 g, of granulated sugar about 200 g, of all-purpose flour about 125 g, of rolled oats about 90 g and of butter 227 g. The converter above has the exact figure for each ingredient.
Is a US cup the same as a UK cup?
No. A US cup is 236.6 ml, a metric cup used in the UK, Australia and most of Europe is 250 ml, about 6 percent more. Old UK recipes sometimes mean an imperial cup of 284 ml. The converter lets you pick which one.
Why do recipes use cups at all?
Habit, mostly American. Cups measure volume, which works for liquids and fails for anything you can pack, like flour or brown sugar. Weights in grams are what professional kitchens and most recipes outside the US use.
How many grams in a tablespoon?
A tablespoon is 15 ml, so 15 g of water, about 14 g of butter, 12 g of sugar and 8 g of flour. A teaspoon is 5 ml: 5 g of water, 4 g of sugar, 3 g of flour.
Where do these numbers come from?
From the USDA food composition database, which records the weight of household measures for each food. How firmly a dry ingredient is packed still changes the weight, so use scales when a recipe depends on precision.
