About Converting Grams per Gallon to Kilograms per Imperial gallon
Gram per Gallon and Kilogram 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
kilograms per imperial gallon = grams per gallon × 0.0012009499255
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 kilogram per imperial gallon equals 219.969248299 base units, so dividing one by the other gives the direct gram per gallon-to-kilogram per imperial gallon factor of 0.0012009499255.
Simple example
1 g/gal × 0.001200949926 = 0.0012009499 kg/imp gal
1 gram per gallon = 0.0012009499 kilograms per imperial gallon.
Real-world example
1,000 g/gal × 0.001200949926 = 1.200949926 kg/imp gal
1,000 grams per gallon = 1.200949926 kilograms per imperial gallon.

What is a gram per gallon?
Gram per Gallon (g/gal) is a unit of density.
What is a kilogram per imperial gallon?
Kilogram per Imperial gallon (kg/imp gal) measures density. A mathematically valid way to express liquid density in kilograms per imperial gallon. It is classified as a mixed metric/UK customary density unit.
Is the gram per gallon to kilogram per imperial gallon conversion exact?
