Formula and Step-by-Step

grams ÷ 144g/cup × 48 = teaspoons
  1. Start with 100 grams of active dry yeast
  2. 1 cup of active dry yeast = 144g
  3. 100g ÷ 144g/cup = 0.69 cups × 48 = 33.33 teaspoons

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 active dry yeast rather than relying on volume.

Understanding the Units

What is a Gram?

Weighing ingredients in grams eliminates the variability of volume measurements. A cup of flour can weigh anywhere from 120g to 160g depending on how it was scooped, but 120g of flour is always 120g of flour.

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 33.33 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 100 grams: 100 ÷ 144 = 0.69 cups × 48 = 33.33 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: 33.33 tsp ÷ 48 = 0.694444 cups, then 0.694444 × 144g/cup = 100g. Or use the Teaspoons to Grams converter.
