About Converting Troy ounces per Fluid ounce to Drams per Imperial gallon
Troy ounce per Fluid ounce and Dram per Imperial gallon both measure density — mass per unit volume — a property used to identify materials, check manufacturing quality, and predict whether something floats or sinks. As a fixed reference point, water has a density of exactly 1000 kg/m³ (1 g/cm³, 1 g/mL) at its temperature of maximum density, which is why many density figures in science and engineering are quoted relative to water. Both are mass per volume density units.
Formula
drams per imperial gallon = troy ounces per fluid ounce × 2698.47271947
