About Converting Drams per Quart to Megagrams per Gallon
Dram per Quart 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 = drams per quart × 0.00000708738078125
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per quart equals 1.87228792683 base units, and 1 megagram per gallon equals 264172.052358 base units, so dividing one by the other gives the direct dram per quart-to-megagram per gallon factor of 0.00000708738078125.
Simple example
1 dr/qt × 0.000007087380781 = 0.0000070874 Mg/gal
1 dram per quart = 0.0000070874 megagrams per gallon.
Real-world example
1,000 dr/qt × 0.000007087380781 = 0.0070873808 Mg/gal
1,000 drams per quart = 0.0070873808 megagrams per gallon.

What is a dram per quart?
Dram per Quart (dr/qt) is a unit of density.
What is a megagram per gallon?
Megagram per Gallon (Mg/gal) is a unit of density.
Is the dram per quart to megagram per gallon conversion exact?
Yes. Both dram per quart and megagram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 0.000007087380781 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.
