Formula and Step-by-Step

cups × 258g/cup = grams

  2. 1 cup of peanut butter = 258g
  3. 0.33 × 258 = 85.14g

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

Measuring Tip

Spoon peanut butter into the measuring cup and pack gently to fill gaps. Do not scoop directly from the jar, which traps air.

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 85.14 g, based on peanut butter having a density of 258g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of cups by 258 (grams per cup for peanut butter). For 0.33 cups: 0.33 × 258 = 85.14 g.
For the most accurate results, weigh peanut butter 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.
