All-purpose flour 120 g per US cup · King Arthur. Example values.
How this is calculated
Each ingredient has a density in grams per US cup (236.6 ml) from King Arthur Baking’s ingredient weight chart. Volume ↔ weight uses that density; volume ↔ volume and weight ↔ weight don’t need one.
grams = ml × (g per US cup ÷ 236.588) · metric cup 250 ml · US cup 236.6 ml · 1 oz = 28.35 g
Why does my cup weigh something different?
How you fill the cup matters. King Arthur’s figures assume flour spooned into the cup and levelled; scooping packs in up to 20% more.
Metric cup or US cup?
Australia, New Zealand, Canada and the UK use a 250 ml cup; the US cup is 236.6 ml. The Metric | US setting picks one; the Cup chip overrides it for this session only.
