Mayonnaise in Grams: 1 Cup, ½ Cup, Tablespoon Conversions
1 cup of mayonnaise weighs 224 grams. Mayonnaise is used in both cooking and baking — in cakes and muffins it adds fat and moisture, and the volume can significantly affect the result. Light or reduced-fat mayonnaise has a higher water content and weighs slightly less per cup; use the same brand and style the recipe specifies.
For the most accurate results, weigh your mayonnaise with a digital kitchen scale — the values below assume a level, unpacked cup.

Who is this useful for?
If you're an international cook following US-based recipes, you'll often encounter cup measurements for mayonnaise. However, many countries — including those in Europe and Asia — primarily use grams for precision. Converting mayonnaise to grams ensures consistent and reliable results, whether you're baking or cooking.
Why accuracy matters for mayonnaise
Precision is especially important when using mayonnaise in baking and cooking. Even small variations in weight can impact the texture, consistency, and flavour of your dish. For example, too much mayonnaise in a recipe can make baked goods dense, while too little may cause them to be too dry or crumbly.
Common mistakes to avoid when cooking with mayonnaise
- Confusing light mayonnaise with regular in baking — the water content differs, which affects moisture in cakes and dressings.
- Adding mayonnaise to hot dishes directly from the jar, causing it to split rather than emulsify.
- Overmixing mayonnaise into batters, which can make the result greasy rather than moist.
