Formula and Step-by-Step

cups × 160g/cup ÷ 28.3495g/oz = ounces
  1. Start with 158 cups of onions (diced)
  2. 1 cup of onions (diced) = 160g
  3. 158 × 160 = 25,280g
  4. Convert grams to ounces: 25,280 ÷ 28.3495 = 891.73 oz

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Measuring Tip

The weight of diced produce per cup depends on how finely it is cut. Smaller dice packs more tightly and weighs more per cup than large chunks.

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.

Frequently Asked Questions

About 891.73 oz, 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.
Multiply the number of cups by 160 (grams per cup for onions (diced)), then divide by 28.3495 to convert grams to ounces. For 158 cups: 158 × 160 = 25,280g, then 25,280 ÷ 28.3495 = 891.73 oz.
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: 891.73 oz × 28.3495 = 25,280g, then 25,280g ÷ 160 = 158 cups. Or use the Ounces to Cups converter.
