Formula and Step-by-Step

(ounces × 28.35g/oz) ÷ 258g/cup = cups
  1. Start with 5.01 ounces of peanut butter
  2. Convert ounces to grams: 5.01 × 28.35 = 142.03g
  3. 1 cup of peanut butter = 258g
  4. 142.03g ÷ 258g/cup = 0.55 cups

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 an Ounce?

An ounce (oz) is a US customary unit of weight equal to 28.3495 grams or 1/16 of a pound. In cooking, "ounces" refers to weight (avoirdupois ounces), not fluid ounces which measure volume.

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.

Frequently Asked Questions

About 0.55 cups, 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.
First convert ounces to grams (1 ounce = 28.3495g), then divide by 258 (grams per cup). For 5.01 ounces: 5.01 × 28.3495 = 142.03g, then 142.03 ÷ 258 = 0.55 cups.
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.
Reverse the conversion: 0.55 cups × 258g/cup = 142.03g, then 142.03g ÷ 28.3495 = 5.01 ounces. Or use the Cups to Ounces converter.
