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 a Gram?

A gram (g) is a metric unit of mass equal to 1/1000 of a kilogram. It is the standard weight measurement for precise baking worldwide. Professional bakers prefer grams because they are more accurate than volume measurements.

Frequently Asked Questions

About 387.00 g, 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.
Multiply the number of teaspoons by 3 (grams per teaspoon for active dry yeast). For 129 teaspoons: 129 × 3 = 387.00 g.
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: 387.00 g ÷ 3 = 129 teaspoons. Or use the Grams to Teaspoons converter.
