Formula and Step-by-Step
- Start with 4 pounds of peanut butter
- Convert pounds to grams: 4 × 453.59 = 1,814.37g
- 1 cup of peanut butter = 258g
- 1,814.37g ÷ 258g/cup = 7.03 cups
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Pounds are the standard weight unit for buying ingredients in the US. A standard bag of flour is 5 pounds (2,268g) and a standard bag of sugar is 4 pounds (1,814g).
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.
