About Converting Drams per Gallon to Drams per Imperial gallon
Dram per Gallon and Dram 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
drams per imperial gallon = drams per gallon × 1.2009499255
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per gallon equals 0.468071981707 base units, and 1 dram per imperial gallon equals 0.389751455715 base units, so dividing one by the other gives the direct dram per gallon-to-dram per imperial gallon factor of 1.2009499255.
Simple example
1 dr/gal × 1.200949926 = 1.200949926 dr/imp gal
1 dram per gallon = 1.200949926 drams per imperial gallon.
Real-world example
1,000 dr/gal × 1.200949926 = 1,200.949926 dr/imp gal
1,000 drams per gallon = 1,200.949926 drams per imperial gallon.
