How Much Is 1 Ounce of Mayonnaise in Cups?
Converting 1 ounce of mayonnaise to cups gives 0.13 cups. First convert to grams (1 oz = 28.35g), then divide by the density of mayonnaise (220g per cup). Each ingredient fills a different volume at the same weight.
Formula and Step-by-Step
- Start with 1 ounce of mayonnaise
- Convert ounces to grams: 1 × 28.35 = 28.35g
- 1 cup of mayonnaise = 220g
- 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.

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.
