About Converting Megagrams per Imperial gallon to Pounds per Cup
Megagram per Imperial gallon and Pound per Cup 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 cup = megagrams per imperial gallon × 114.733271504
This factor comes from each unit's defined relationship to the category's base unit: 1 megagram per imperial gallon equals 219969.248299 base units, and 1 pound per cup equals 1917.22283707 base units, so dividing one by the other gives the direct megagram per imperial gallon-to-pound per cup factor of 114.733271504.
Simple example
1 Mg/imp gal × 114.7332715 = 114.7332715 lb/cup
1 megagram per imperial gallon = 114.7332715 pounds per cup.
