What this calculator estimates
Convert cups to grams using an editable ingredient density, with volume and serving equivalents.
How to use it
Enter Number of US cups; Ingredient grams per US cup. Select Calculate to update the results.
How the calculation works
The calculator multiplies cups by the entered grams-per-cup density and separately converts US cup volume to milliliters and tablespoons.
Worked example: starting scenario
| Number of US cups | 2 |
|---|---|
| Ingredient grams per US cup | 120 |
| Estimated grams | 240 g |
|---|---|
| Approximate ounces by weight | 8.46575087 oz |
| Approximate milliliters of volume | 473.176473 mL |
| Equivalent tablespoons | 32 |
| Grams per half cup | 60 g |
Important limitations
Grams per cup vary widely by ingredient and packing method, so use a density appropriate to the specific ingredient.
Mass conversion needs an ingredient assumption
US cup volume is fixed at 236.5882365 mL in this form, but mass depends on the ingredient and packing. At 120 grams per cup, two cups weigh 240 grams; at 200 grams per cup, the same volume weighs 400 grams. The grams-per-half-cup output uses half the entered density, regardless of the number of cups selected. A metric 250 mL cup needs a different volume basis.
