Formula and Step-by-Step

(pounds × 453.59g/lb) ÷ 220g/cup = cups
  1. Start with 1.5 pounds of mayonnaise
  2. Convert pounds to grams: 1.5 × 453.59 = 680.39g
  3. 1 cup of mayonnaise = 220g
  4. 680.39g ÷ 220g/cup = 3.09 cups

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

Measuring Tip

Mayonnaise should be spooned into the measuring cup and leveled off. Do not scoop directly from the jar, which traps air.

Frequently Asked Questions

About 3.09 cups, based on mayonnaise having a density of 220g per cup. The exact amount depends on how the ingredient is measured and the specific product.
First convert pounds to grams (1 pound = 453.592g), then divide by 220 (grams per cup). For 1.5 pounds: 1.5 × 453.592 = 680.39g, then 680.39 ÷ 220 = 3.09 cups.
For the most accurate results, weigh mayonnaise 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.
Fat content has a small effect on density. Higher-fat versions are slightly lighter per volume because fat is less dense than water. The difference is usually under 5%, so this conversion works well for standard varieties.
Reverse the conversion: 3.09 cups × 220g/cup = 680.39g, then 680.39g ÷ 453.592 = 1.5 pounds. Or use the Cups to Pounds converter.
