About Converting Drams per Tablespoon to Pounds per Imperial gallon
Dram per Tablespoon and Pound per Imperial 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
pounds per imperial gallon = drams per tablespoon × 1.2009499255
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per tablespoon equals 119.826427317 base units, and 1 pound per imperial gallon equals 99.7763726631 base units, so dividing one by the other gives the direct dram per tablespoon-to-pound per imperial gallon factor of 1.2009499255.
