Formula and Step-by-Step

(ounces × 28.35g/oz) ÷ 160g/cup × 16 = tablespoons
  1. Start with 0.18 ounces of onions (diced)
  2. Convert ounces to grams: 0.18 × 28.35 = 5.10g
  3. 1 cup of onions (diced) = 160g
  4. 5.10g ÷ 160g/cup = 0.03 cups × 16 = 0.51 tablespoons

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 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.

What is a Tablespoon?

A tablespoon is roughly the volume of a large soup spoon. In precise terms, 1 US tablespoon equals 14.787 ml, which is very close to the 15 ml metric standard used in most of the world. Three teaspoons make one tablespoon.

Frequently Asked Questions

About 0.51 tbsp, 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), then multiply by 16 to get tablespoons. For 0.18 ounces: 0.18 × 28.3495 = 5.10g, then 5.10 ÷ 160 = 0.03 cups × 16 = 0.51 tbsp.
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: 0.51 tbsp ÷ 16 = 0.0318932 cups, then 0.0318932 × 160g/cup = 5.10g, then 5.10g ÷ 28.3495 = 0.18 ounces. Or use the Tablespoons to Ounces converter.
