Cup to Gram Calculator — How It Works

Converts cooking measurements like cups, tablespoons, and grams, accounting for ingredient density.

How it works

  1. Enter the amount you want to convert.
  2. Choose the unit you’re converting from (cups, tablespoons, teaspoons, milliliters, grams, or ounces).
  3. Choose the unit you’re converting to.
  4. Choose the ingredient — the tool uses its density to convert accurately between volume and weight.

Formula

Volume (mL) = Amount × Volume conversion factor
Weight (g) = Volume (mL) × Ingredient density (g/mL)

Example

1 cup of flour converts to about 140 g, using flour’s density of roughly 0.593 g/mL.

Why this matters

A cup of flour and a cup of sugar don’t weigh the same — volume-to-weight conversions depend on the ingredient’s density. This is especially important for baking, where weighing ingredients gives more consistent results than measuring by volume.
