About Converting Kilograms per Gallon to Kilograms per Imperial gallon
Kilogram 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. Kilogram per Gallon is most often used for can be used to express liquid density such as fuel or industrial liquids in kilograms per gallon — in practice, kilograms per liter (metric) and pounds per gallon (us customary) are the specific pairings more commonly seen in fuel and liquid-density references.
Formula
kilograms per imperial gallon = kilograms per gallon × 1.2009499255
This factor comes from each unit's defined relationship to the category's base unit: 1 kilogram per gallon equals 264.172052358 base units, and 1 kilogram per imperial gallon equals 219.969248299 base units, so dividing one by the other gives the direct kilogram per gallon-to-kilogram per imperial gallon factor of 1.2009499255.
Simple example
1 kg/gal × 1.200949926 = 1.200949926 kg/imp gal
1 kilogram per gallon = 1.200949926 kilograms per imperial gallon.
Real-world example
1,000 kg/gal × 1.200949926 = 1,200.949926 kg/imp gal
1,000 kilograms per gallon = 1,200.949926 kilograms per imperial gallon.
