Formula and Step-by-Step

tablespoons × 7g/tbsp ÷ 28.3495g/oz = ounces
  1. Start with 40.5 tablespoons of onion powder
  2. 1 tablespoon of onion powder = 7g
  3. 40.5 × 7 = 283.5g
  4. Convert grams to ounces: 283.5 ÷ 28.3495 = 10.00 oz

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

Measuring Tip

For the most accurate results, weigh onion powder on a kitchen scale. At small quantities, even slight over-measuring can overpower a dish.

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 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 10.00 oz, based on onion powder having a density of 112g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of tablespoons by 7 (grams per tablespoon for onion powder), then divide by 28.3495 to convert grams to ounces. For 40.5 tablespoons: 40.5 × 7 = 283.5g, then 283.5 ÷ 28.3495 = 10.00 oz.
For the most accurate results, weigh onion powder 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: 10.00 oz × 28.3495 = 283.5g, then 283.5g ÷ 7 = 40.5 tablespoons. Or use the Ounces to Tablespoons converter.
