About Converting Troy ounces per Tablespoon to Drams per Gallon
Troy ounce per Tablespoon and Dram 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
drams per gallon = troy ounces per tablespoon × 4493.89714286
This factor comes from each unit's defined relationship to the category's base unit: 1 troy ounce per tablespoon equals 2103.46734124 base units, and 1 dram per gallon equals 0.468071981707 base units, so dividing one by the other gives the direct troy ounce per tablespoon-to-dram per gallon factor of 4493.89714286.
