About the Cooking Measurement Converter
Converts between common cooking volume units (teaspoon through gallon, milliliter, liter) and weight units (gram through kilogram), including volume-to-weight conversions for a few specific ingredients using real published densities — since a cup of flour and a cup of water weigh very different amounts.
- Enter the amount and choose the unit you're converting from and to.
- If converting between a volume and a weight unit, select the specific ingredient.
- Read the converted amount.
1 cup of all-purpose flour converts to exactly 120.00g, while 1 cup of granulated sugar converts to 200.00g and 1 cup of water converts to 236.59g — three different weights for the identical 1-cup volume.
| Ingredient | Grams per cup |
|---|---|
| Water (reference) | 236.59g |
| All-purpose flour | 120g |
| Granulated sugar | 200g |
| Butter | 227g |
Volume-to-weight conversion depends entirely on what you're measuring — offered only for a handful of specifically sourced ingredients rather than a generic assumption. Weigh unlisted ingredients directly on a kitchen scale instead of guessing a density.
- • For baking, weighing ingredients gives far more consistent results than volume measurements.
- • If your ingredient isn't flour, sugar, butter, or water, weigh it directly rather than guessing.
- • Volume-to-volume conversions are always exact regardless of ingredient.
