Cooking Measurement Converter
One cup of flour is 125g. One cup of sugar is 200g. It depends on the ingredient.
Convert cups, tablespoons and teaspoons to grams. A cup of one ingredient does not weigh the same as a cup of another, so pick the ingredient first. Weights come from USDA FoodData Central, with the source and the date we checked it on every ingredient. Ingredients that are not in the source are left out. What you type stays on this device.

One cup of the usual suspects
| Flour, white, all-purpose (bleached) | 1cup = 125g |
|---|---|
| Sugar, granulated | 1cup = 200g |
| Sugar, brown (packed) | 1cup = 220g |
| Butter, salted | 1cup = 227g |
| Water | 1cup = 237g |
| Honey | 1cup = 339g |
| Rice, white, long-grain, raw | 1cup = 185g |
| Cocoa, dry powder, unsweetened | 1cup = 86g |
A cup is not the same everywhere
How much a recipe's cup holds depends on which country wrote it. The grams here use the US customary cup.
| Standard | Volume | vs US cup | Basis |
|---|---|---|---|
| US customary cup | 237 mL | 100% | defined exactly |
| US nutrition-labeling cup | 240 mL | 101% | in regulation |
| Metric cup | 250 mL | 106% | convention |
| Korean / Japanese cup | 200 mL | 85% | convention |
Values marked convention are widely used, but we could not find them in an official document. The 200mL Korean cup is one of them. We do not claim a standards body set it.
There is no UK row. Schedule 1 of the Weights and Measures Act 1985 lists gallons, pints and fluid ounces, but no cup at all.
A Korean cup holds less
The Korean measuring cup is 200mL and the US cup is about 237mL. Scooping one US cup with a Korean cup gives you about 15% less. Weighing in grams avoids the gap.
Tablespoons and teaspoons
| Standard | tbsp | tsp | Basis |
|---|---|---|---|
| US | 14.8 mL | 4.93 mL | defined exactly |
| Metric (incl. Korea) | 15 mL | 5 mL | in regulation |

What this page does not do
Every weight is copied from USDA data. We invented none of them. Ingredients the source does not list are left out. Density shifts with humidity and with how you fill the cup, so treat these as reference weights, not measurements of your own flour. For baking, use a scale. This page has no account, no saving and no notifications.
