About Converting Megagrams per Gallon to Megagrams per Imperial gallon
Megagram per Gallon and Megagram 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
megagrams per imperial gallon = megagrams per gallon × 1.2009499255
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 megagram per imperial gallon equals 219969.248299 base units, so dividing one by the other gives the direct megagram per gallon-to-megagram per imperial gallon factor of 1.2009499255.
Simple example
1 Mg/gal × 1.200949926 = 1.200949926 Mg/imp gal
1 megagram per gallon = 1.200949926 megagrams per imperial gallon.
Real-world example
1,000 Mg/gal × 1.200949926 = 1,200.949926 Mg/imp gal
1,000 megagrams per gallon = 1,200.949926 megagrams per imperial gallon.

What is a megagram per gallon?
Megagram per Gallon (Mg/gal) is a unit of density.
What is a megagram per imperial gallon?
Megagram per Imperial gallon (Mg/imp gal) is a unit of density.
Is the megagram per gallon to megagram per imperial gallon conversion exact?
Yes. Both megagram per gallon and megagram per imperial gallon are defined by fixed standards rather than physical artifacts, so the factor of 1.200949926 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.
