How Much Is 1 Cup of Walnuts in Grams?
1 cup of walnuts weighs 120.00 g. This is based on walnuts having a density of 120g per cup. Because cups measure volume and grams measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 1 cup.
Formula and Step-by-Step
- Start with 1 cup of walnuts
- 1 cup of walnuts = 120g
- 1 × 120 = 120g
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Mental Math Shortcut
For 1 cup of walnuts, just remember: 120g. Double it for 2 cups (240g), halve it for a half cup (60g).
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.
