Flour Cups to Grams

Pick your flour and enter cups, tablespoons, grams or ounces to see the same amount in every unit.

Fractions work too, such as 2/3 or 1 1/2. Changing the unit keeps the same amount of flour.

Weights are for flour spooned into the cup and leveled, King Arthur Baking’s method. Flour scooped from the bag packs down and can weigh up to a third more, so weigh it when the recipe gives grams.

How it works

Every flour has its own weight per cup, so the converter multiplies or divides by the weight of one cup of the flour you picked:

grams = cups × grams per cup

cups = grams ÷ grams per cup

Tablespoons are 1/16 of a cup, and ounces are turned into grams first (1 oz = 28.35 g). The weights per cup come from King Arthur Baking’s Ingredient Weight Chart.

Worked example

  1. A recipe calls for 2 1/2 cups of bread flour. Bread flour weighs 120 g a cup.
  2. 2.5 × 120 = 300 g, which is 10.6 oz.
  3. The same 2 1/2 cups of whole wheat flour, at 113 g a cup, would be 2.5 × 113 = 283 g.

FAQ

How many grams are in a cup of flour?

A cup of all-purpose flour weighs 120 g (4 1/4 oz) by King Arthur Baking’s chart, and bread flour weighs the same. Other flours differ: whole wheat is 113 g a cup, rye 106 g, almond flour 96 g and semolina 163 g. Pick your flour in the converter to see its weight.

Why do other sites say a cup of flour is 125 g or more?

Because a cup of flour has no fixed weight; it depends on how you fill it. Spooned in and leveled, a cup holds about 120 g. Scooped straight from the bag it packs down, and King Arthur Baking notes a tightly packed cup can hold as much as 160 g. Some sites assume a heavier scoop, so their numbers run higher.

How do I measure flour by the cup to match these weights?

Use King Arthur Baking’s method: stir the flour in its bag or canister to loosen it, spoon it into the measuring cup until it heaps over the top, then scrape off the excess with a straight edge. Do not shake or tap the cup. A kitchen scale is still more accurate, and it is the only way to repeat a dough exactly.

Is a cup of bread flour heavier than all-purpose?

Not by enough to matter. King Arthur Baking lists both at 120 g a cup. Bread flour has more protein, which changes how much water it absorbs, but not how much fits in a cup.

How many cups is 500 g of flour?

About 4 cups plus 3 tablespoons of all-purpose or bread flour, at 120 g a cup. Of whole wheat flour, at 113 g a cup, it is about 4 1/4 cups plus 3 tablespoons. Enter 500 g in the converter to see it for every flour.
