Formula and Step-by-Step

teaspoons × 4.79g/tsp ÷ 28.3495g/oz = ounces
  1. Start with 8 teaspoons of baking powder
  2. 1 teaspoon of baking powder = 4.79g
  3. 8 × 4.79 = 38.33g
  4. Convert grams to ounces: 38.33 ÷ 28.3495 = 1.35 oz

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

Measuring Tip

Leavener measurements are critical because even small differences affect rise and texture. When possible, weigh baking powder rather than relying on volume.

Understanding the Units

What is a Teaspoon?

One teaspoon holds about 5 milliliters. There are 3 teaspoons in a tablespoon and 48 teaspoons in a cup. Teaspoon accuracy matters most with leaveners like baking powder and baking soda, where small differences affect rise and texture.

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 1.35 oz, based on baking powder having a density of 230g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of teaspoons by 4.79 (grams per teaspoon for baking powder), then divide by 28.3495 to convert grams to ounces. For 8 teaspoons: 8 × 4.79 = 38.33g, then 38.33 ÷ 28.3495 = 1.35 oz.
For the most accurate results, weigh baking 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.
