Formula and Step-by-Step

cups × 220g/cup ÷ 28.3495g/oz = ounces
  1. Start with 1 cup of mayonnaise
  2. 1 cup of mayonnaise = 220g
  3. 1 × 220 = 220g
  4. Convert grams to ounces: 220 ÷ 28.3495 = 7.76 oz

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

Measuring Tip

For the most accurate results, weigh mayonnaise on a kitchen scale. Thick spreads can vary by 5-10% depending on how firmly they are packed.

Understanding the Units

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.

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.

Frequently Asked Questions

About 7.76 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 cup: 1 × 220 = 220g, then 220 ÷ 28.3495 = 7.76 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: 7.76 oz × 28.3495 = 220g, then 220g ÷ 220 = 1 cup. Or use the Ounces to Cups converter.
