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?

In baking, teaspoon measurements are critical for ingredients where precision changes the outcome. Too much baking soda (1 tsp = 6g) creates a metallic taste, while too little means flat results.

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.

Frequently Asked Questions

About 449.22 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 149.74 teaspoons: 149.74 × 3 = 449.22 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: 449.22 g ÷ 3 = 149.74 teaspoons. Or use the Grams to Teaspoons converter.
