Formula and Step-by-Step

cups × 120g/cup = grams
  1. Start with 1.51 cups of walnuts
  2. 1 cup of walnuts = 120g
  3. 1.51 × 120 = 181.2g

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?

A cup is a US customary unit of volume equal to 236.588 milliliters or 8 fluid ounces. It is the most common volume measurement in American recipes. One cup can be divided into 16 tablespoons or 48 teaspoons.

What is a Gram?

Weighing ingredients in grams eliminates the variability of volume measurements. A cup of flour can weigh anywhere from 120g to 160g depending on how it was scooped, but 120g of flour is always 120g of flour.

Frequently Asked Questions

About 181.20 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 1.51 cups: 1.51 × 120 = 181.20 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: 181.20 g ÷ 120 = 1.51 cups. Or use the Grams to Cups converter.
