  1. Start with 1.5 cups of mayonnaise
  2. 1 cup of mayonnaise = 220g
  3. 1.5 × 220 = 330g
  4. Convert grams to ounces: 330 ÷ 28.3495 = 11.64 oz

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

Frequently Asked Questions

About 11.64 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 1.5 cups: 1.5 × 220 = 330g, then 330 ÷ 28.3495 = 11.64 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: 11.64 oz × 28.3495 = 330g, then 330g ÷ 220 = 1.5 cups. Or use the Ounces to Cups converter.
