Convert Cups to Grams: Cake Flour
Convert cups of cake flour to grams with this complete reference table. 1 cup of cake flour = 100g (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 cake flour density can vary by measuring technique.
Cake Flour Cups to Grams Table
| Cups | Grams |
|---|---|
| 1/8 cup | 12.5g |
| 1/4 cup | 25g |
| 1/3 cup | 33.3g |
| 1/2 cup | 50g |
| 2/3 cup | 66.7g |
| 3/4 cup | 75g |
| 1 cup | 100g |
| 1 1/4 cups | 125g |
| 1 1/2 cups | 150g |
| 2 cups | 200g |
| 3 cups | 300g |
| 4 cups | 400g |
Based on USDA FoodData Central data (1 US cup = 240ml = 16 tablespoons = 48 teaspoons). Note: Cake flour is the lightest of all wheat flours. Very finely milled with low protein (7-9%). 1 cup = 100g (sifted). Always sift cake flour before measuring. Used for tender cakes, delicate pastries.
About Cake Flour Density
The density of cake flour determines how much it weighs per unit of volume. At 0.417g/ml, 1 US cup (240ml) of cake flour weighs 100g 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 cake flour?
1 cup of cake flour weighs 100 grams (USDA FoodData Central, spooned-and-leveled method, 1 US cup = 240ml).
How many grams is 1/2 cup of cake flour?
1/2 cup of cake flour weighs 50 grams.
How many grams is 1/4 cup of cake flour?
1/4 cup of cake flour weighs 25 grams.
Does measuring technique affect the weight of cake flour?
Yes. Sifted cake flour can weigh up to 20% less than packed or scooped. The USDA standard (spooned-and-leveled) of 100g/cup is the most reliable baseline.
