How Much Is 100 Grams of Peanut Butter in Cups?
100 grams of peanut butter equals 0.39 cups. Peanut butter has a density of 258g per cup. A lighter ingredient like flour (125g/cup) would fill more volume at the same weight, which is why ingredient-specific conversions matter.
Formula and Step-by-Step
- Start with 100 grams of peanut butter
- 1 cup of peanut butter = 258g
- 100g ÷ 258g/cup = 0.39 cups
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Understanding the Units
What is a Gram?
A gram (g) is a metric unit of mass equal to 1/1000 of a kilogram. It is the standard weight measurement for precise baking worldwide. Professional bakers prefer grams because they are more accurate than volume measurements.
What is a Cup?
There are three cup standards used worldwide. The US cup (236.588 ml) is used in American recipes. The metric cup (250 ml) is standard in Australia, New Zealand, and some parts of Asia. The imperial cup (284.131 ml) appears in older British and Canadian recipes. A metric cup holds about 5.7% more than a US cup, while an imperial cup holds about 20% more. Using the wrong standard can noticeably affect a recipe.
