About Converting Kilograms per Imperial gallon to Long tons per Cubic Meter
Kilogram per Imperial gallon and Long ton per Cubic Meter 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 Imperial gallon is most often used for can be used to express liquid density in uk/commonwealth contexts that reference the imperial gallon — in practice, kilograms per liter is the more commonly seen metric density unit even in these regions.
Formula
long tons per cubic meter = kilograms per imperial gallon × 0.21649517005
This factor comes from each unit's defined relationship to the category's base unit: 1 kilogram per imperial gallon equals 219.969248299 base units, and 1 long ton per cubic meter equals 1016.0469088 base units, so dividing one by the other gives the direct kilogram per imperial gallon-to-long ton per cubic meter factor of 0.21649517005.
Simple example
1 kg/imp gal × 0.21649517 = 0.21649517 long ton/m3
1 kilogram per imperial gallon = 0.21649517 long tons per cubic meter.
Real-world example
1,000 kg/imp gal × 0.21649517 = 216.49517 long ton/m3
1,000 kilograms per imperial gallon = 216.49517 long tons per cubic meter.

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.
What is a long ton per cubic meter?
Long ton per Cubic Meter (long ton/m3) is a unit of density.
Is the kilogram per imperial gallon to long ton per cubic meter conversion exact?
Yes. Both kilogram per imperial gallon and long ton per cubic meter are defined by fixed standards rather than physical artifacts, so the factor of 0.21649517 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.
