Convert Cups to Grams: Tapioca Flour (Starch)
Convert cups of tapioca flour (starch) to grams with this complete reference table. 1 cup of tapioca flour (starch) = 120g (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 tapioca flour (starch) density can vary by measuring technique.
Tapioca Flour (Starch) Cups to Grams Table
| Cups | Grams |
|---|---|
| 1/8 cup | 15g |
| 1/4 cup | 30g |
| 1/3 cup | 40g |
| 1/2 cup | 60g |
| 2/3 cup | 80g |
| 3/4 cup | 90g |
| 1 cup | 120g |
| 1 1/4 cups | 150g |
| 1 1/2 cups | 180g |
| 2 cups | 240g |
| 3 cups | 360g |
| 4 cups | 480g |
Based on USDA FoodData Central data (1 US cup = 240ml = 16 tablespoons = 48 teaspoons). Note: Tapioca flour/starch: 1 cup = 120g. Extracted from cassava root. Very fine, white powder. Used as a thickener (like cornstarch) and in gluten-free baking blends. Adds chewiness to baked goods. 1 tablespoon tapioca starch = 1 tablespoon cornstarch for thickening. USDA FDC 20070.
About Tapioca Flour (Starch) Density
The density of tapioca flour (starch) determines how much it weighs per unit of volume. At 0.5g/ml, 1 US cup (240ml) of tapioca flour (starch) weighs 120g 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.
Frequently Asked Questions
How many grams is 1 cup of tapioca flour (starch)?
1 cup of tapioca flour (starch) weighs 120 grams (USDA FoodData Central, spooned-and-leveled method, 1 US cup = 240ml).
How many grams is 1/2 cup of tapioca flour (starch)?
1/2 cup of tapioca flour (starch) weighs 60 grams.
