About Converting Dram per Cubic inches to Pounds per Imperial gallon
Dram per Cubic inch 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 = dram per cubic inches × 1.08366965934
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per cubic inch equals 108.124627774 base units, and 1 pound per imperial gallon equals 99.7763726631 base units, so dividing one by the other gives the direct dram per cubic inch-to-pound per imperial gallon factor of 1.08366965934.
