About Converting Grams per Gallon to Centigrams per Imperial gallon
Gram per Gallon and Centigram 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
centigrams per imperial gallon = grams per gallon × 120.09499255
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 centigram per imperial gallon equals 0.00219969248299 base units, so dividing one by the other gives the direct gram per gallon-to-centigram per imperial gallon factor of 120.09499255.
Simple example
1 g/gal × 120.0949926 = 120.0949926 cg/imp gal
1 gram per gallon = 120.0949926 centigrams per imperial gallon.
Real-world example
1,000 g/gal × 120.0949926 = 120,094.9926 cg/imp gal
1,000 grams per gallon = 120,094.9926 centigrams per imperial gallon.

What is a gram per gallon?
Gram per Gallon (g/gal) is a unit of density.
What is a centigram per imperial gallon?
Centigram per Imperial gallon (cg/imp gal) is a unit of density.
Is the gram per gallon to centigram per imperial gallon conversion exact?
Yes. Both gram per gallon and centigram per imperial gallon are defined by fixed standards rather than physical artifacts, so the factor of 120.0949926 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.
