  2. 1 teaspoon of cream of tartar = 3g
  3. 1.5 × 3 = 4.5g

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 cream of tartar rather than relying on volume.

Understanding the Units

What is a Teaspoon?

A teaspoon (tsp) is a US customary unit of volume equal to 4.929 milliliters or 1/3 of a tablespoon. It is the standard measure for spices, leaveners, extracts, and other small-quantity ingredients.

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 4.50 g, based on cream of tartar 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 cream of tartar). For 1.5 teaspoons: 1.5 × 3 = 4.50 g.
For the most accurate results, weigh cream of tartar 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: 4.50 g ÷ 3 = 1.5 teaspoons. Or use the Grams to Teaspoons converter.
