How Much Is 1 Ounce of Mayonnaise in Cups?

Formula and Step-by-Step

(ounces × 28.35g/oz) ÷ 220g/cup = cups
  1. Start with 1 ounce of mayonnaise
  2. Convert ounces to grams: 1 × 28.35 = 28.35g
  3. 1 cup of mayonnaise = 220g
  4. 28.35g ÷ 220g/cup = 0.13 cups

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 an Ounce?

Weight ounces and fluid ounces are different measurements. A fluid ounce measures volume (29.574 ml), while an ounce measures weight (28.35g). They only align for water, where 1 fl oz weighs approximately 1 oz.

What is a Cup?

The US cup (236.588 ml) is slightly smaller than the metric cup used in Australia and some other countries (250 ml). When following recipes from different countries, check which cup standard is being used.

Frequently Asked Questions

About 0.13 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 ounces to grams (1 ounce = 28.3495g), then divide by 220 (grams per cup). For 1 ounce: 1 × 28.3495 = 28.35g, then 28.35 ÷ 220 = 0.13 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: 0.13 cups × 220g/cup = 28.35g, then 28.35g ÷ 28.3495 = 1 ounce. Or use the Cups to Ounces converter.
