About Converting Megagrams per Cup to Long tons per Imperial gallon
Megagram per Cup and Long ton 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
long tons per imperial gallon = megagrams per cup × 18.9117240963
This factor comes from each unit's defined relationship to the category's base unit: 1 megagram per cup equals 4226752.83773 base units, and 1 long ton per imperial gallon equals 223499.074765 base units, so dividing one by the other gives the direct megagram per cup-to-long ton per imperial gallon factor of 18.9117240963.
Simple example
1 Mg/cup × 18.9117241 = 18.9117241 long ton/imp gal
1 megagram per cup = 18.9117241 long tons per imperial gallon.
Real-world example
1,000 Mg/cup × 18.9117241 = 18,911.7241 long ton/imp gal
1,000 megagrams per cup = 18,911.7241 long tons per imperial gallon.

What is a megagram per cup?
Megagram per Cup (Mg/cup) is a unit of density.
What is a long ton per imperial gallon?
Long ton per Imperial gallon (long ton/imp gal) is a unit of density.
Is the megagram per cup to long ton per imperial gallon conversion exact?
Yes. Both megagram per cup and long ton per imperial gallon are defined by fixed standards rather than physical artifacts, so the factor of 18.9117241 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.
