Formula and Step-by-Step

(ounces × 28.35g/oz) ÷ 160g/cup = cups
  1. Start with 4.01 ounces of onions (diced)
  2. Convert ounces to grams: 4.01 × 28.35 = 113.68g
  3. 1 cup of onions (diced) = 160g
  4. 113.68g ÷ 160g/cup = 0.71 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?

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.

Frequently Asked Questions

About 0.71 cups, based on onions (diced) having a density of 160g per cup. The exact amount depends on how the ingredient is measured and the specific product.
First convert ounces to grams (1 ounce = 28.3495g), then divide by 160 (grams per cup). For 4.01 ounces: 4.01 × 28.3495 = 113.68g, then 113.68 ÷ 160 = 0.71 cups.
For the most accurate results, weigh onions (diced) on a kitchen scale. If measuring by volume, spoon the ingredient into the measuring cup and level it off with a straight edge rather than scooping directly.
Weight-per-cup values vary because of differences in how the ingredient is measured (spooned vs scooped), grind size, moisture content, and settling during storage. Our values use standardized measurement methods from established culinary references.
Reverse the conversion: 0.71 cups × 160g/cup = 113.68g, then 113.68g ÷ 28.3495 = 4.01 ounces. Or use the Cups to Ounces converter.
