Working with all-purpose flour

All-Purpose Flour sits in the flours & starches group, where a cup lands in the same range as water, but the material still compacts differently depending on how you fill the cup. Spoon the flour into the cup and level with a knife. Dipping the cup straight into the bag compacts it and can give you 145–150 g instead of 120 g.

If you are converting a whole recipe rather than a single line, the Recipe to Metric converter matches every ingredient to its own density in one pass, and the Recipe Scaler resizes the batch first so you only convert once.

Also sold as: plain flour, ap flour. These names refer to the same product and use the same weight per cup.
