Formula and Step-by-Step

cups × 220g/cup ÷ 453.592g/lb = pounds
  1. Start with 1.55 cups of mayonnaise
  2. 1 cup of mayonnaise = 220g
  3. 1.55 × 220 = 341g
  4. Convert grams to pounds: 341 ÷ 453.592 = 0.75 lb

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

Measuring Tip

Mayonnaise weighs 220g per cup. Low-fat and regular mayonnaise 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 a Pound?

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).

Frequently Asked Questions

About 0.75 lb, based on mayonnaise having a density of 220g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of cups by 220 (grams per cup for mayonnaise), then divide by 453.592 to convert grams to pounds. For 1.55 cups: 1.55 × 220 = 341g, then 341 ÷ 453.592 = 0.75 lb.
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: 0.75 lb × 453.592 = 341g, then 341g ÷ 220 = 1.55 cups. Or use the Pounds to Cups converter.
