About Converting Megagrams per Quart to Imperial hundredweights per Gallon
Megagram per Quart and Imperial hundredweight 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
imperial hundredweights per gallon = megagrams per quart × 78.7365222089
This factor comes from each unit's defined relationship to the category's base unit: 1 megagram per quart equals 1056688.20943 base units, and 1 imperial hundredweight per gallon equals 13420.5598595 base units, so dividing one by the other gives the direct megagram per quart-to-imperial hundredweight per gallon factor of 78.7365222089.
Simple example
1 Mg/qt × 78.73652221 = 78.73652221 long cwt/gal
1 megagram per quart = 78.73652221 imperial hundredweights per gallon.

What is a megagram per quart?
Megagram per Quart (Mg/qt) is a unit of density.
What is a imperial hundredweight per gallon?
Imperial hundredweight per Gallon (long cwt/gal) is a unit of density.
Is the megagram per quart to imperial hundredweight per gallon conversion exact?
Yes. Both megagram per quart and imperial hundredweight per gallon are defined by fixed standards rather than physical artifacts, so the factor of 78.73652221 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.
