About Converting Drams per Imperial gallon to Megagrams per Quart
Dram per Imperial gallon and Megagram per Quart 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 quart = drams per imperial gallon × 3.688424e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per imperial gallon equals 0.389751455715 base units, and 1 megagram per quart equals 1056688.20943 base units, so dividing one by the other gives the direct dram per imperial gallon-to-megagram per quart factor of 3.688424e-7.
Simple example
1 dr/imp gal × 3.688424e-7 = 3.688424e-7 Mg/qt
1 dram per imperial gallon = 3.688424e-7 megagrams per quart.
Real-world example
1,000 dr/imp gal × 3.688424e-7 = 0.0003688424 Mg/qt
1,000 drams per imperial gallon = 0.0003688424 megagrams per quart.

What is a dram per imperial gallon?
Dram per Imperial gallon (dr/imp gal) is a unit of density.
What is a megagram per quart?
Megagram per Quart (Mg/qt) is a unit of density.
Is the dram per imperial gallon to megagram per quart conversion exact?
Yes. Both dram per imperial gallon and megagram per quart are defined by fixed standards rather than physical artifacts, so the factor of 3.688424e-7 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.
