Convert Cups to Grams: Cream of Tartar
Convert cups of cream of tartar to grams with this complete reference table. 1 cup of cream of tartar = 239g (USDA FoodData Central, spooned-and-leveled method). Use the table below for fractions from 1/8 cup up to 4 cups. For precision baking, weight measurements in grams are always more reliable than volume measurements in cups, because cream of tartar density can vary by measuring technique.

Based on USDA FoodData Central data (1 US cup = 240ml = 16 tablespoons = 48 teaspoons). Note: Cream of tartar: 1 teaspoon = 5g. Stabilizes egg whites in meringues. Mix 2 parts cream of tartar + 1 part baking soda = baking powder substitute. Also prevents sugar crystallization in candy making.
About Cream of Tartar Density
The density of cream of tartar determines how much it weighs per unit of volume. At 0.996g/ml, 1 US cup (240ml) of cream of tartar weighs 239g under USDA standard conditions.
Volume measurements can vary by ±10–20% depending on technique (sifted vs. spooned vs. scooped). For consistent baking results, use a kitchen scale with gram measurements whenever possible. The USDA standard (spooned-and-leveled) is the reference point for all values on this page.
