How Much Is 5 Cups of Peanut Butter in Ounces?
5 cups of peanut butter equals 45.50 oz. Peanut butter has a density of 258g per cup (258g per cup), which means it's relatively heavy compared to other common cooking ingredients. For comparison, 5 cups of all-purpose flour would be 22.07 oz.
Formula and Step-by-Step
- Start with 5 cups of peanut butter
- 1 cup of peanut butter = 258g
- 5 × 258 = 1,290g
- Convert grams to ounces: 1,290 ÷ 28.3495 = 45.50 oz
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Peanut butter weighs 258g per cup. Natural and processed versions may have slightly different densities.

Understanding the Units
What is a Cup?
In US cooking, a cup measures volume, not weight. One standard US cup holds 236.588 ml of liquid. Because different ingredients have different densities, a cup of one ingredient can weigh very differently from a cup of another.
What is an Ounce?
Ounces are commonly used in US recipes for cheese, meat, chocolate, and other ingredients sold by weight. Many kitchen scales offer both gram and ounce readings.
