How cups to ingredient weight works
Estimate grams from US cups using explicit reference weights.
Formula and convention
Grams = cups x the displayed reference weight per cup.A worked example
One cup of flour at the 120 g/cup convention is 120 g; two cups are 240 g.
Scope and precision
Planning conventions, not exact constants. Packing, scooping, humidity, grain type, and brand affect weight. Weigh ingredients for repeatable baking.
