How It Works

How to Convert Cups to Grams

Formula

Grams = Cups x Density (g/cup)

Cup-to-gram conversions depend on the ingredient because each ingredient has a different density. Flour is much lighter per cup than sugar or butter.

Why Weight Matters in Baking

Measuring by weight is more accurate than measuring by volume. A cup of flour can vary by 30 g depending on how it is scooped.

Worked Example

Convert 2 cups of all-purpose flour to grams.

cups = 2density = 125
  1. 01Identify the density of all-purpose flour: 125 g per cup.
  2. 02Multiply: 2 cups x 125 g/cup = 250 g.
  3. 03The result is 250 grams of flour.
