About Converting Drams per Gallon to Grams per Imperial gallon
Dram per Gallon and Gram 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
grams per imperial gallon = drams per gallon × 2.12789735532
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 gram per imperial gallon equals 0.219969248299 base units, so dividing one by the other gives the direct dram per gallon-to-gram per imperial gallon factor of 2.12789735532.
Simple example
1 dr/gal × 2.127897355 = 2.127897355 g/imp gal
1 dram per gallon = 2.127897355 grams per imperial gallon.
Real-world example
1,000 dr/gal × 2.127897355 = 2,127.897355 g/imp gal
1,000 drams per gallon = 2,127.897355 grams per imperial gallon.

What is a dram per gallon?
Dram per Gallon (dr/gal) is a unit of density.
What is a gram per imperial gallon?
Gram per Imperial gallon (g/imp gal) is a unit of density.
Is the dram per gallon to gram per imperial gallon conversion exact?
Yes. Both dram per gallon and gram per imperial gallon are defined by fixed standards rather than physical artifacts, so the factor of 2.127897355 used above is exact to as many digits as you choose to display.
What's the difference between density and mass concentration?
Density is the mass of a pure substance or material per unit volume. Mass concentration is the mass of one component — like a dissolved solute — within a mixture's total volume. The two use the same kind of units but describe different physical situations.
