Formula and Step-by-Step

cups × 220g/cup ÷ 28.3495g/oz = ounces
  1. Start with 20.62 cups of mayonnaise
  2. 1 cup of mayonnaise = 220g
  3. 20.62 × 220 = 4,536.4g
  4. Convert grams to ounces: 4,536.4 ÷ 28.3495 = 160.02 oz

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.

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 an Ounce?

Ounces are commonly used in US recipes for cheese, meat, chocolate, and other ingredients sold by weight. Many kitchen scales offer both gram and ounce readings.

Frequently Asked Questions

About 160.02 oz, 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 28.3495 to convert grams to ounces. For 20.62 cups: 20.62 × 220 = 4,536.4g, then 4,536.4 ÷ 28.3495 = 160.02 oz.
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: 160.02 oz × 28.3495 = 4,536.4g, then 4,536.4g ÷ 220 = 20.62 cups. Or use the Ounces to Cups converter.
