Formula and Step-by-Step

grams ÷ 144g/cup × 48 = teaspoons
  1. Start with 64 grams of active dry yeast
  2. 1 cup of active dry yeast = 144g
  3. 64g ÷ 144g/cup = 0.44 cups × 48 = 21.33 teaspoons

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 Gram?

Grams are the preferred unit in professional kitchens and bakeries because they allow exact recipe scaling. To double a recipe, simply double the gram values. No need to worry about how tightly an ingredient is packed into a cup.

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.

Frequently Asked Questions

About 21.33 tsp, based on active dry yeast having a density of 144g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Divide the grams by 144 (grams per cup) to get cups, then multiply by 48 to get teaspoons. For 64 grams: 64 ÷ 144 = 0.44 cups × 48 = 21.33 tsp.
For the most accurate results, weigh active dry yeast 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: 21.33 tsp ÷ 48 = 0.444444 cups, then 0.444444 × 144g/cup = 64g. Or use the Teaspoons to Grams converter.
