Recipes use cups in one country and grams in another. A cup is a volume, a gram is a weight, and ingredients differ in density, so "one cup equals so many grams" depends on what is in the cup.
Quick answer
Choose the ingredient, enter an amount and unit, and read the equivalent in cups, spoons, millilitres, ounces and grams. The numbers are good averages for home cooking.
Typical weights of one cup
| Ingredient | Grams per cup (approx.) |
|---|---|
| Plain flour | 120 to 125 |
| Granulated sugar | 200 |
| Brown sugar (packed) | 210 |
| Icing sugar | 120 |
| Butter | 227 |
| Rice (uncooked) | 185 |
| Water or milk | 240 |
| Honey | 340 |
Spoon sizes
- 1 tablespoon = 15 ml (3 teaspoons).
- 1 teaspoon = 5 ml.
- A cup is 240 ml in the US system and 250 ml in many other countries.
Tips for accurate results
- Weigh when you can. Baking is chemistry; grams are more reliable than cups.
- Spoon and level flour. Scooping packs the flour and can add 20 percent.
- Check the cup type. American, metric and Japanese cups differ.
- Do not mix systems within one recipe.
Steps
- Pick an ingredient.
- Enter the amount and its unit.
- Read the converted values.
