About Converting Megagrams per Imperial gallon to Long tons per Gallon
Megagram 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 = megagrams per imperial gallon × 0.819523367885
This factor comes from each unit's defined relationship to the category's base unit: 1 megagram per imperial gallon equals 219969.248299 base units, and 1 long ton per gallon equals 268411.19719 base units, so dividing one by the other gives the direct megagram per imperial gallon-to-long ton per gallon factor of 0.819523367885.
Simple example
1 Mg/imp gal × 0.8195233679 = 0.8195233679 long ton/gal
1 megagram per imperial gallon = 0.8195233679 long tons per gallon.
Real-world example
1,000 Mg/imp gal × 0.8195233679 = 819.5233679 long ton/gal
1,000 megagrams per imperial gallon = 819.5233679 long tons per gallon.

Multiply the megagram per imperial gallon value by 0.8195233679. The converter above does this instantly to whatever precision you set.
How do I convert long ton per gallon back to megagram per imperial gallon?
Use the reverse factor: 1 long ton per gallon equals 1.220221459 megagrams per imperial gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a megagram per imperial gallon?
Megagram 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 megagram per imperial gallon to long ton per gallon conversion exact?
Yes. Both megagram per imperial gallon and long ton per gallon are defined by fixed standards rather than physical artifacts, so the factor of 0.8195233679 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.
