About Converting Megagrams per Gallon to Long tons per Imperial gallon
Megagram per Gallon and Long ton 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
long tons per imperial gallon = megagrams per gallon × 1.18198275602
This factor comes from each unit's defined relationship to the category's base unit: 1 megagram per gallon equals 264172.052358 base units, and 1 long ton per imperial gallon equals 223499.074765 base units, so dividing one by the other gives the direct megagram per gallon-to-long ton per imperial gallon factor of 1.18198275602.
Simple example
1 Mg/gal × 1.181982756 = 1.181982756 long ton/imp gal
1 megagram per gallon = 1.181982756 long tons per imperial gallon.
Real-world example
1,000 Mg/gal × 1.181982756 = 1,181.982756 long ton/imp gal
1,000 megagrams per gallon = 1,181.982756 long tons per imperial gallon.

Frequently asked questions
How many long tons per imperial gallon are in 1 megagram per gallon?
1 megagram per gallon equals 1.181982756 long tons per imperial gallon, using the exact defined conversion factor rather than an estimate.
How do I convert megagram per gallon to long ton per imperial gallon?
Multiply the megagram per gallon value by 1.181982756. The converter above does this instantly to whatever precision you set.
How do I convert long ton per imperial gallon back to megagram per gallon?
Use the reverse factor: 1 long ton per imperial gallon equals 0.8460360313 megagrams per gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a megagram per gallon?
Megagram per Gallon (Mg/gal) is a unit of density.
What is a long ton per imperial gallon?
Long ton per Imperial gallon (long ton/imp gal) is a unit of density.
Is the megagram per gallon to long ton per imperial gallon conversion exact?
Yes. Both megagram per gallon and long ton per imperial gallon are defined by fixed standards rather than physical artifacts, so the factor of 1.181982756 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.
