How many grams are in a cup of mayonnaise?

A cup of mayonnaise weighs about 220 grams, which is roughly 7.76 ounces. This figure applies to standard full-fat mayonnaise at room temperature.

How many grams are in a tablespoon of mayonnaise?

Since there are 16 tablespoons in a cup, one tablespoon of mayonnaise weighs about 13.75 grams using the same 220 g/cup density.

How many grams are in a teaspoon of mayonnaise?

Since there are 48 teaspoons in a cup, one teaspoon of mayonnaise weighs about 4.58 grams using the same 220 g/cup density.

Is 220 grams per cup an exact figure?

No, it is an approximation. Brand, egg and oil ratio, and how the mayonnaise is scooped into the cup all affect the actual weight. For baking or dressing recipes where precision matters, weigh the mayonnaise on a kitchen scale instead of relying on a cup measure.

Does light or reduced-fat mayonnaise weigh the same as regular?

Light mayonnaise replaces some oil with water and stabilizers, which can shift the density slightly from the 220 g/cup figure used here for regular mayonnaise.

Is this a US cup or a metric cup?

This tool uses the US cup (236.6 ml). A metric cup (250 ml) would give a slightly higher gram result.
