How Much Is 4 Ounces of Mayonnaise in Cups?
4 ounces of mayonnaise equals 0.52 cups. Mayonnaise has a density of 220g per cup. A lighter ingredient like flour (125g/cup) would fill more volume at the same weight, which is why ingredient-specific conversions matter.
Formula and Step-by-Step
- Start with 4 ounces of mayonnaise
- Convert ounces to grams: 4 × 28.35 = 113.40g
- 1 cup of mayonnaise = 220g
- 113.40g ÷ 220g/cup = 0.52 cups
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
For the most accurate results, weigh mayonnaise on a kitchen scale. Thick spreads can vary by 5-10% depending on how firmly they are packed.

Understanding the Units
What is an Ounce?
Weight ounces and fluid ounces are different measurements. A fluid ounce measures volume (29.574 ml), while an ounce measures weight (28.35g). They only align for water, where 1 fl oz weighs approximately 1 oz.
What is a Cup?
In US cooking, a cup measures volume, not weight. One standard US cup holds 236.588 ml of liquid. Because different ingredients have different densities, a cup of one ingredient can weigh very differently from a cup of another.
