Where the figure comes from
The weight on this page is from the King Arthur Baking ingredient weight chart, which lists cake flour as 1 cup = 120 g. Scaled to one US cup of 236.59 ml, that is 120 g. Every other number on the page is that figure multiplied or divided.
The chart entry is for: Unbleached cake flour.
grams = cups x 120
cups = grams / 120
For example, 1 1/2 cups of cake flour is 1.5 x 120 = 180 g, and 300 g is 300 / 120 = 2.5 cups.
How cake flour compares by the cup
A cup measures volume, so its weight depends on what fills it. A cup of cake flour is 47.1 percent lighter than a cup of water (227 g). It is the same as a cup of all-purpose flour (120 g).
Other flours from the same chart, per US cup:
- All-purpose flour: 120 g
- Bread flour: 120 g
- Whole wheat flour: 113 g, 7 g less than cake flour
- Self-rising flour: 113 g, 7 g less than cake flour
- Pastry flour: 106 g, 14 g less than cake flour
- Rye flour: 106 g, 14 g less than cake flour
- Almond flour: 96 g, 24 g less than cake flour
Nutrition in a cup of cake flour
These figures apply USDA FoodData Central values for wheat flour, white, cake, enriched to the 120 g cup used on this page.

The two sources do not agree on what a cup weighs. USDA lists a cup of this food at 137 g, which is 17 g more than the 120 g in the baking chart. Products and the way a cup is filled both differ, which is the reason a recipe that gives grams is easier to repeat than one that gives cups. This page uses the baking chart figure throughout.
US cup or metric cup
A US cup is 236.59 ml and a metric cup, used in Australia, New Zealand and Canada, is 250 ml. The metric cup is 5.7 percent larger, so it holds 127 g of cake flour against 120 g. Tablespoons and teaspoons on this page are US spoons. The calculator above has a switch for the cup size.
