How Much Is 0.5 Cups of Peanut Butter in Grams?
0.5 cups of peanut butter weighs 129.00 g. This is based on peanut butter having a density of 258g 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 0.5 cups.
Formula and Step-by-Step
- Start with 0.5 cups of peanut butter
- 1 cup of peanut butter = 258g
- 0.5 × 258 = 129g
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Mental Math Shortcut
Half measures: take the weight of 1 cup (258g) and divide by 2.
Measuring Tip
Peanut butter should be stirred before measuring if the oil has separated. An unmixed jar will give inconsistent measurements.
