About

Cupsgram is a free, independent kitchen-conversion site. We convert volume to weight using ingredient densities from the King Arthur Baking Ingredient Weight Chart, applied to the US customary cup (236.59 ml). Unit constants follow NIST definitions (1 oz = 28.3495 g, 1 lb = 453.592 g).

Volume measurements are inherently approximate; for best results use a kitchen scale.
