About Converting Pounds per Imperial gallon to Megagrams per Gallon
Pound per Imperial gallon and Megagram 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
megagrams per gallon = pounds per imperial gallon × 0.000377694656844
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per imperial gallon equals 99.7763726631 base units, and 1 megagram per gallon equals 264172.052358 base units, so dividing one by the other gives the direct pound per imperial gallon-to-megagram per gallon factor of 0.000377694656844.
Simple example
1 lb/imp gal × 0.0003776946568 = 0.0003776947 Mg/gal
1 pound per imperial gallon = 0.0003776947 megagrams per gallon.
Real-world example
1,000 lb/imp gal × 0.0003776946568 = 0.3776946568 Mg/gal
1,000 pounds per imperial gallon = 0.3776946568 megagrams per gallon.

What is a pound per imperial gallon?
Pound per Imperial gallon (lb/imp gal) is a unit of density.
What is a megagram per gallon?
Megagram per Gallon (Mg/gal) is a unit of density.
Is the pound per imperial gallon to megagram per gallon conversion exact?
Yes. Both pound per imperial gallon and megagram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 0.0003776946568 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.
