How Much Is 8.79 Cups of Peanut Butter in Pounds?
8.79 cups of peanut butter weighs 5.00 lb. This is based on peanut butter having a density of 258g per cup. Because cups measure volume and pounds measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 8.79 cups.
Formula and Step-by-Step
- Start with 8.79 cups of peanut butter
- 1 cup of peanut butter = 258g
- 8.79 × 258 = 2,267.82g
- Convert grams to pounds: 2,267.82 ÷ 453.592 = 5.00 lb
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Peanut butter should be stirred before measuring if the oil has separated. An unmixed jar will give inconsistent measurements.

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 a Pound?
The abbreviation "lb" comes from the Latin word "libra." One pound equals exactly 453.59237 grams. For rough mental math, 1 pound is slightly less than half a kilogram.
