About Converting Ounces per Imperial gallon to Drams per Teaspoon
Ounce per Imperial gallon and Dram per Teaspoon 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 teaspoon = ounces per imperial gallon × 0.0173473788464
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per imperial gallon equals 6.23602329144 base units, and 1 dram per teaspoon equals 359.479281951 base units, so dividing one by the other gives the direct ounce per imperial gallon-to-dram per teaspoon factor of 0.0173473788464.
