Formula and Step-by-Step
- Start with 0.5 cups of onions (diced)
- 1 cup of onions (diced) = 160g
- 0.5 × 160 = 80g
- Convert grams to ounces: 80 ÷ 28.3495 = 2.82 oz
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Raw and cooked produce have very different weights per cup. Cooked vegetables shrink and become denser. These conversions are for raw produce.

Understanding the Units
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.
What is an Ounce?
An ounce (oz) is a US customary unit of weight equal to 28.3495 grams or 1/16 of a pound. In cooking, "ounces" refers to weight (avoirdupois ounces), not fluid ounces which measure volume.
