About Converting Grams per Gallon to Drams per Imperial gallon
Gram 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 = grams per gallon × 0.67779619161
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per gallon equals 0.264172052358 base units, and 1 dram per imperial gallon equals 0.389751455715 base units, so dividing one by the other gives the direct gram per gallon-to-dram per imperial gallon factor of 0.67779619161.
Simple example
1 g/gal × 0.6777961916 = 0.6777961916 dr/imp gal
1 gram per gallon = 0.6777961916 drams per imperial gallon.
Real-world example
1,000 g/gal × 0.6777961916 = 677.7961916 dr/imp gal
1,000 grams per gallon = 677.7961916 drams per imperial gallon.

What is a gram per gallon?
Gram per Gallon (g/gal) is a unit of density.
What is a dram per imperial gallon?
Dram per Imperial gallon (dr/imp gal) is a unit of density.
Is the gram per gallon to dram per imperial gallon conversion exact?
Yes. Both gram per gallon and dram per imperial gallon are defined by fixed standards rather than physical artifacts, so the factor of 0.6777961916 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.
