Formula and Step-by-Step
- Start with 3 cups of mayonnaise

- 3 × 220 = 660g
- Convert grams to ounces: 660 ÷ 28.3495 = 23.28 oz
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Mayonnaise should be spooned into the measuring cup and leveled off. Do not scoop directly from the jar, which traps air.
