About Converting Troy ounces per Gallon to Drams per Liter
Troy ounce per Gallon and Dram per Liter 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 liter = troy ounces per gallon × 4.63735168482
This factor comes from each unit's defined relationship to the category's base unit: 1 troy ounce per gallon equals 8.21666930173 base units, and 1 dram per liter equals 1.77184519531 base units, so dividing one by the other gives the direct troy ounce per gallon-to-dram per liter factor of 4.63735168482.
