Formula and Step-by-Step

tablespoons × 10g/tbsp ÷ 28.3495g/oz = ounces
  1. Start with 15 tablespoons of onions (diced)
  2. 1 tablespoon of onions (diced) = 10g
  3. 15 × 10 = 150g
  4. Convert grams to ounces: 150 ÷ 28.3495 = 5.29 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 Tablespoon?

Tablespoon sizes differ by country. A US tablespoon is 14.787 ml, close to the 15 ml metric standard used in most countries. An Australian tablespoon is 20 ml, about 35% larger than US. An imperial tablespoon is 17.758 ml. If your recipe comes from Australia, the larger tablespoon size can make a real difference.

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.

Frequently Asked Questions

About 5.29 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 tablespoons by 10 (grams per tablespoon for onions (diced)), then divide by 28.3495 to convert grams to ounces. For 15 tablespoons: 15 × 10 = 150g, then 150 ÷ 28.3495 = 5.29 oz.
For the most accurate results, weigh onions (diced) on a kitchen scale. If measuring by volume, spoon the ingredient into the measuring spoon 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: 5.29 oz × 28.3495 = 150g, then 150g ÷ 10 = 15 tablespoons. Or use the Ounces to Tablespoons converter.
