Formula and Step-by-Step

teaspoons × 4.58g/tsp ÷ 28.3495g/oz = ounces
  1. Start with 66.67 teaspoons of baking soda
  2. 1 teaspoon of baking soda = 4.58g
  3. 66.67 × 4.58 = 305.57g

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

Measuring Tip

Baking powder loses potency over time. If yours is more than 6 months old, test it: drop a teaspoon into hot water. If it bubbles vigorously, it is still active.

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?

Ounces are commonly used in US recipes for cheese, meat, chocolate, and other ingredients sold by weight. Many kitchen scales offer both gram and ounce readings.

Frequently Asked Questions

About 10.78 oz, based on baking soda having a density of 220g per cup. The exact amount depends on how the ingredient is measured and the specific product.

For the most accurate results, weigh baking soda 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.
