About coffee measurements
Whole coffee beans are mostly air when measured by volume — a reference density near 0.37 g/ml, just 86 g per US cup. Roast level matters: dark roasts puff up lighter than dense light roasts, and the irregular beans leave gaps that make cup measures unreliable next to a scale.
