About Converting Milligrams per Imperial gallon to Long tons per Gallon
Milligram per Imperial gallon and Long ton per 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
long tons per gallon = milligrams per imperial gallon × 8.195234e-10
This factor comes from each unit's defined relationship to the category's base unit: 1 milligram per imperial gallon equals 0.000219969248299 base units, and 1 long ton per gallon equals 268411.19719 base units, so dividing one by the other gives the direct milligram per imperial gallon-to-long ton per gallon factor of 8.195234e-10.
Simple example
1 mg/imp gal × 8.195234e-10 = 8.195234e-10 long ton/gal
1 milligram per imperial gallon = 8.195234e-10 long tons per gallon.
Real-world example
1,000 mg/imp gal × 8.195234e-10 = 8.195234e-7 long ton/gal
1,000 milligrams per imperial gallon = 8.195234e-7 long tons per gallon.

What is a milligram per imperial gallon?
Milligram per Imperial gallon (mg/imp gal) is a unit of density.
What is a long ton per gallon?
Long ton per Gallon (long ton/gal) is a unit of density.
Is the milligram per imperial gallon to long ton per gallon conversion exact?
Yes. Both milligram per imperial gallon and long ton per gallon are defined by fixed standards rather than physical artifacts, so the factor of 8.195234e-10 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.
