Formula and Step-by-Step

teaspoons × 3g/tsp ÷ 28.3495g/oz = ounces
  1. Start with 0.5 teaspoons of cream of tartar
  2. 1 teaspoon of cream of tartar = 3g
  3. 0.5 × 3 = 1.5g
  4. Convert grams to ounces: 1.5 ÷ 28.3495 = 0.05 oz

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

Measuring Tip

Cream of tartar can clump or settle during storage. Stir or sift before measuring by volume for consistent results.

Understanding the Units

What is a Teaspoon?

A US teaspoon is 4.929 ml, a metric teaspoon is exactly 5 ml, and an imperial teaspoon is 5.919 ml. The metric and US versions are nearly identical (1.4% difference), but the imperial teaspoon is 20% larger. For most spices the difference is negligible, but for leaveners like baking powder it can affect the result.

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 0.05 oz, based on cream of tartar having a density of 144g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of teaspoons by 3 (grams per teaspoon for cream of tartar), then divide by 28.3495 to convert grams to ounces. For 0.5 teaspoons: 0.5 × 3 = 1.5g, then 1.5 ÷ 28.3495 = 0.05 oz.
