Formula and Step-by-Step

tablespoons × 10g/tbsp = grams
  1. Start with 30 tablespoons of onions (diced)
  2. 1 tablespoon of onions (diced) = 10g
  3. 30 × 10 = 300g

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?

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.

What is a Gram?

Weighing ingredients in grams eliminates the variability of volume measurements. A cup of flour can weigh anywhere from 120g to 160g depending on how it was scooped, but 120g of flour is always 120g of flour.

Frequently Asked Questions

About 300.00 g, 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)). For 30 tablespoons: 30 × 10 = 300.00 g.
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: 300.00 g ÷ 10 = 30 tablespoons. Or use the Grams to Tablespoons converter.
