Coconut Flour: Grams to Cups
1 cup of coconut flour = 128 grams
One US cup of coconut flour weighs 128 grams. One 250 ml metric cup — the one used in the UK, Australia, New Zealand and Canada — holds 135 grams. To convert any weight, divide the grams by the figure for your cup.
Coconut flour weighs 128 g per cup (King Arthur Baking). It is extremely absorbent, so recipes use far less of it than wheat flour — often ¼ to ⅓ as much, with extra eggs.
Why you should never swap it cup for cup
Coconut flour is the dried, defatted pulp left after coconut milk is pressed out. It is mostly fibre and absorbs several times its weight in liquid. A cup of it will turn a batter written for 1 cup of all-purpose flour into a dry paste.
The rule of thumb in coconut-flour baking is roughly ¼ cup of coconut flour and one extra egg for every cup of wheat flour replaced, then adjusting liquid until the batter looks right. Recipes developed for coconut flour are far more reliable than conversions.
Measuring small amounts accurately
Because recipes use so little, a heaped tablespoon (about 10–11 g) against a level one (8 g) matters more than it would with wheat flour. Sift or whisk out lumps, spoon it in and level it, or better, weigh it.
Storing it and what to bake with it
Coconut flour keeps well in an airtight container in a cool cupboard for several months, longer in the fridge. It works best in dense, moist bakes — muffins, pancakes, brownies — where its fibre holds moisture rather than drying the crumb. Let a coconut-flour batter rest for five minutes before judging its thickness: the flour keeps absorbing liquid after mixing.

How to measure coconut flour accurately
The 128 g figure assumes the spooned-and-levelled method: spoon the coconut flour into a dry measuring cup and sweep the top flat with a straight edge. Scooping the cup through the bag compacts it and gives a heavier cup.
- 1 US cup of coconut flour = 128 g
- 1 metric cup (250 ml) of coconut flour = 135 g
- ¾ cup = 96 g
- ½ cup = 64 g
- ⅓ cup = 43 g
- ¼ cup = 32 g
- 1 tablespoon = 8.0 g
