About Converting Troy ounces per Teaspoon to Drams per Gallon
Troy ounce per Teaspoon 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 teaspoon × 13481.6914286
This factor comes from each unit's defined relationship to the category's base unit: 1 troy ounce per teaspoon equals 6310.40202373 base units, and 1 dram per gallon equals 0.468071981707 base units, so dividing one by the other gives the direct troy ounce per teaspoon-to-dram per gallon factor of 13481.6914286.
