Why coconut flour needs its own conversion
Coconut Flour weighs about 128g per cup — quite light and airy compared to many kitchen staples. King Arthur = 128 g/cup; other sources cite 112-120 g. Highly variable by brand; sift to remove lumps. A cup is a unit of volume, so ingredients this different in density can't share one generic conversion factor — using a single "1 cup = X g" rule for everything will be wrong for at least some of what you cook.
Common measurement mistakes
- Using a generic cup-to-gram factor for every ingredient — coconut flour does not weigh the same per cup as most other ingredients.
- Measurement note: King Arthur = 128 g/cup; other sources cite 112-120 g. Highly variable by brand; sift to remove lumps.
- Confusing weight ounces with fluid ounces when a recipe lists "oz" — they are not interchangeable.

It’s a close approximation based on King Arthur Baking. Minor variations in moisture, grain, or brand can shift the exact weight slightly, but this figure works well for everyday cooking and baking.
