Quick Answer
One US cup of whole wheat flour weighs about 120 grams. That works out to 7.5 g per tablespoon and 2.5 g per teaspoon. Whole-grain flours vary 10-15 g per cup by brand. Weights vary slightly by brand, moisture, and how tightly you pack - for precise baking, a kitchen scale beats volume measures.

Frequently Asked Questions
How many grams in 1 cup of whole wheat flour?
About 120 grams, scoop-and-level for dry ingredients. Whole-grain flours vary 10-15 g per cup by brand.
How many grams in a tablespoon of whole wheat flour?
One US tablespoon (15 mL) of whole wheat flour is about 7.5 grams. A teaspoon is 2.5 g.
Why does whole wheat flour weigh more (or less) than water?
Dry ingredients are weighed by how they pack into the cup volume. Whole Wheat Flour has an apparent density of about 0.51 g/mL - lighter than water - depending on particle size and air gaps.
How many cups is 100 g of whole wheat flour?
100 g ÷ 120 g/cup ≈ 0.83 cups - about a little less than a full cup. The reverse table on this page covers 25-1000 g.
Should I weigh or measure by volume?
Weighing is more accurate - volume measures vary with how you scoop, pack, and level, and brands differ by 5-15%. For cookies and cakes where ratios matter, grams are the professional standard. The tables here convert either direction.
