Mayonnaise: Grams to Cups
1 cup of mayonnaise = 220 grams
One US cup of mayonnaise weighs 220 grams. One 250 ml metric cup — the one used in the UK, Australia, New Zealand and Canada — holds 232 grams. To convert any weight, divide the grams by the figure for your cup.
A cup of regular mayonnaise weighs 220 g, the household measure USDA FoodData Central records for regular mayonnaise (13.8 g per tablespoon). Light and reduced-fat mayonnaise is heavier per cup, not lighter, because water replaces some of the oil: USDA weighs reduced-fat mayonnaise with olive oil at 232 g a cup. Spoon it into a dry measuring cup and level it, or weigh it straight into the bowl.

How to measure mayonnaise accurately
The 220 g figure assumes the spooned-and-levelled method: spoon the mayonnaise into a dry measuring cup and sweep the top flat with a straight edge. Scooping the cup through the bag compacts it and gives a heavier cup.
