About Converting Centigrams per Gallon to Grams per Imperial gallon
Centigram 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 = centigrams per gallon × 0.012009499255
This factor comes from each unit's defined relationship to the category's base unit: 1 centigram per gallon equals 0.00264172052358 base units, and 1 gram per imperial gallon equals 0.219969248299 base units, so dividing one by the other gives the direct centigram per gallon-to-gram per imperial gallon factor of 0.012009499255.
Simple example
1 cg/gal × 0.01200949926 = 0.0120094993 g/imp gal
1 centigram per gallon = 0.0120094993 grams per imperial gallon.
Real-world example
1,000 cg/gal × 0.01200949926 = 12.00949926 g/imp gal
1,000 centigrams per gallon = 12.00949926 grams per imperial gallon.

What is a centigram per gallon?
Centigram per Gallon (cg/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 centigram per gallon to gram per imperial gallon conversion exact?
Yes. Both centigram per gallon and gram per imperial gallon are defined by fixed standards rather than physical artifacts, so the factor of 0.01200949926 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.
