About ground coffee measurements
Ground coffee packs denser than whole beans, with a reference density around 0.54 g/ml (about 128 g per cup). Grind fineness drives it: espresso-fine grounds settle tightly and weigh more per spoon than a coarse French-press grind, so dialing in a brew by weight beats measuring by scoop.
