Formula and Step-by-Step

cups × 120g/cup = grams
  1. Start with 0.21 cups of walnuts
  2. 1 cup of walnuts = 120g
  3. 0.21 × 120 = 25.2g

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Measuring Tip

When a recipe says "1 cup nuts, chopped" vs "1 cup chopped nuts," the first means measure whole then chop. The second means chop first then measure. The weight difference can be significant.

Understanding the Units

What is a Cup?

The US cup (236.588 ml) is slightly smaller than the metric cup used in Australia and some other countries (250 ml). When following recipes from different countries, check which cup standard is being used.

What is a Gram?

Grams are the preferred unit in professional kitchens and bakeries because they allow exact recipe scaling. To double a recipe, simply double the gram values. No need to worry about how tightly an ingredient is packed into a cup.

Frequently Asked Questions

About 25.20 g, based on walnuts having a density of 120g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of cups by 120 (grams per cup for walnuts). For 0.21 cups: 0.21 × 120 = 25.20 g.
For the most accurate results, weigh walnuts on a kitchen scale. If measuring by volume, spoon the ingredient into the measuring cup and level it off with a straight edge rather than scooping directly.
Weight-per-cup values vary because of differences in how the ingredient is measured (spooned vs scooped), grind size, moisture content, and settling during storage. Our values use standardized measurement methods from established culinary references.
Reverse the conversion: 25.20 g ÷ 120 = 0.21 cups. Or use the Grams to Cups converter.
