All-purpose flour: Cups to Grams

Where the figure comes from

The weight on this page is from the King Arthur Baking ingredient weight chart, which lists all-purpose 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.

grams = cups x 120

cups = grams / 120

For example, 1 1/2 cups of all-purpose flour is 1.5 x 120 = 180 g, and 300 g is 300 / 120 = 2.5 cups.

How all-purpose flour compares by the cup

A cup measures volume, so its weight depends on what fills it. A cup of all-purpose flour is 47.1 percent lighter than a cup of water (227 g).

Other flours from the same chart, per US cup:

• Bread flour: 120 g
• Cake flour: 120 g
• Whole wheat flour: 113 g, 7 g less than all-purpose flour
• Self-rising flour: 113 g, 7 g less than all-purpose flour
• Pastry flour: 106 g, 14 g less than all-purpose flour
• Rye flour: 106 g, 14 g less than all-purpose flour
• Almond flour: 96 g, 24 g less than all-purpose flour

Nutrition in a cup of all-purpose flour

These figures apply USDA FoodData Central values for wheat flour, white, all-purpose, enriched, bleached 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 125 g, which is 5 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 all-purpose flour against 120 g. Tablespoons and teaspoons on this page are US spoons. The calculator above has a switch for the cup size.
