About Converting Megagrams per Cup to Pounds per Imperial gallon
Megagram per Cup and Pound 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
pounds per imperial gallon = megagrams per cup × 42362.2619756
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 pound per imperial gallon equals 99.7763726631 base units, so dividing one by the other gives the direct megagram per cup-to-pound per imperial gallon factor of 42362.2619756.
Simple example
1 Mg/cup × 42362.26198 = 42,362.26198 lb/imp gal
1 megagram per cup = 42,362.26198 pounds per imperial gallon.
Real-world example
1,000 Mg/cup × 42362.26198 = 42,362,261.98 lb/imp gal
1,000 megagrams per cup = 42,362,261.98 pounds per imperial gallon.
