Mayonnaise is an emulsion of oil and egg, and it is dense and creamy. Because it is spooned and scraped rather than poured, small air gaps in the cup are the main source of error. Light and reduced-fat mayonnaise are different products with their own weights, and the cup on this page is for the regular full-fat kind.

What a cup of mayonnaise weighs, and why it can differ

USDA’s weight for “1 cup” is 220 g. Next to a cup of water, which holds about 236.6 g, that is 93% of the weight of a cup of water, so it weighs about the same as the same volume of water. The same cup works out at 0.93 g per millilitre.

USDA lists one cup measure for mayonnaise (“1 cup”), so this page has no second figure to compare it with; if a recipe depends on the exact amount, weigh it.

USDA lists no teaspoon measure for this entry, so that weight is the cup weight divided by the US ratio (48 teaspoons to the cup).

USDA lists slightly different weights for the tablespoon and the teaspoon here: 3 teaspoons come to 13.7 g and 1 tablespoon is 13.8 g. The gap is rounding in the source figures.

How many cups is 500 g of mayonnaise?

If my recipe uses 250 ml metric cups, how much mayonnaise is that?

A 250 ml cup is about 5.7% larger than a US cup, so a metric cup of mayonnaise comes to about 232.5 g, going by USDA’s 220 g for a US cup of mayonnaise. The weights on this page are for the US cup of about 237 ml.

Is it better to weigh mayonnaise than to measure it by the cup?

For baking, yes. USDA lists one cup measure for mayonnaise (“1 cup”), so this page has no second figure to compare it with; if a recipe depends on the exact amount, weigh it. Next to water, a cup of mayonnaise is 93% of the weight of a cup of water, so it weighs about the same as the same volume of water, and 220 g on a scale is 220 g however the mayonnaise was scooped.

What weighs about the same as a cup of mayonnaise?

Among these converters, brown sugar (220 g per cup) and canola oil (218 g per cup) come closest to 220 g. Same volume, different ingredient: the weights are close, but the foods are not interchangeable.
