How many grams are in a cup of flour?
Convert cups, tablespoons and teaspoons to grams for flour, sugar, butter and more.
Quick answer
US cup conversions depend on ingredient density: grams = quantity × cup fraction × grams per cup. One cup of all-purpose flour = 125 g; one tablespoon (1/16 cup) = 125 ÷ 16 ≈ 7.8 g. Butter is denser: 1 cup = 227 g.
Equivalent in grams
125 g
- 1 cup of all-purpose flour
- 125 g
How it works
Volume measures are imprecise for baking — a packed vs sifted cup of flour can differ by 20 g. Weighing in grams gives repeatable results. The calculator includes common staples; for unlisted ingredients, look up grams per cup and multiply.
Frequently asked questions
US cup vs metric cup — are they the same?+
No. A US cup is 240 ml; a metric cup is 250 ml. This calculator uses US cups. For metric cups, multiply results by 250/240 ≈ 1.04.
How many grams in a tablespoon of sugar?+
Granulated sugar: about 12.5 g per tablespoon (200 g per cup ÷ 16). Powdered sugar is lighter (~7.5 g/tbsp).
Can I use ml instead of grams for liquids?+
For water and milk, 1 ml ≈ 1 g. For oil and honey, density differs: 1 cup oil ≈ 218 g, 1 cup honey ≈ 340 g.
Why do European recipes use grams?+
Europe standardised on metric weight; US home kitchens adopted volume measures. Professional bakers everywhere prefer grams for accuracy.
