How Much Is 8 Ounces of Onions (Diced) in Cups?
Converting 8 ounces of onions (diced) to cups gives 1.42 cups. First convert to grams (8 oz = 226.80g), then divide by the density of onions (diced) (160g per cup). Each ingredient fills a different volume at the same weight.
Formula and Step-by-Step
- Start with 8 ounces of onions (diced)
- Convert ounces to grams: 8 × 28.35 = 226.80g
- 1 cup of onions (diced) = 160g
- 226.80g ÷ 160g/cup = 1.42 cups
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 an Ounce?
Ounces are commonly used in US recipes for cheese, meat, chocolate, and other ingredients sold by weight. Many kitchen scales offer both gram and ounce readings.
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.
