Why the ingredient matters

A cup is a volume, not a weight. All-purpose flour has a density of 0.529 g/ml — different ingredients give different weights for the same cup. That's why generic « cup to gram » charts are wrong by 10–30 %.

How precise is this?

The density used here is sourced and cross-checked. Real-world measures still vary by about ±8% depending on how the cup is filled — sifted, scooped or packed.

Frequently asked questions

How many gram is 1 US tablespoon of All-purpose flour?

1 US tablespoon of All-purpose flour equals about 8 gram, using a density of 0.529 g/ml.

Is a US cup the same as a metric cup?

No — a US cup is 236.6 ml, a metric cup 250 ml, an imperial cup 284 ml. This page uses the US cup; the converter lets you switch conventions.

Why do different sites give different answers?
