How the Cups to Grams Calculator works
Enter the number of cups and choose the ingredient.
Each ingredient has a typical weight per US cup.
Real weights vary with how the ingredient is packed, so weigh when precision matters.
The formula
Worked example
Using the default values shown in the calculator:
| Cups | 1.5 |
|---|---|
| Ingredient | All-purpose flour |
- 1.5 cups of all-purpose flour × 125 g per cup = 188 g.
- That is 6.61 oz, or 355 ml by volume.
Result:
| Grams | 188 |
|---|---|
| Ounces | 6.61 |
| Millilitres (volume) | 355 |
| Grams per cup | 125 |
Frequently asked questions
Why do cups of different ingredients weigh differently?
Cups measure volume. A cup of flour is lighter than a cup of sugar or honey because they have different densities.
Why do bakers prefer weighing?
Scooping packs flour differently each time, which can change a cup by 20 g or more. Weighing is repeatable.
