About Converting Drams per Fluid ounce to Troy ounces per Gallon
Dram per Fluid ounce and Troy ounce per 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
troy ounces per gallon = drams per fluid ounce × 7.29166666667
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per fluid ounce equals 59.9132136584 base units, and 1 troy ounce per gallon equals 8.21666930173 base units, so dividing one by the other gives the direct dram per fluid ounce-to-troy ounce per gallon factor of 7.29166666667.
