About Converting Pounds per Imperial gallon to Kilograms per Cup
Pound per Imperial gallon and Kilogram 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
kilograms per cup = pounds per imperial gallon × 0.0236059160527
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per imperial gallon equals 99.7763726631 base units, and 1 kilogram per cup equals 4226.75283773 base units, so dividing one by the other gives the direct pound per imperial gallon-to-kilogram per cup factor of 0.0236059160527.
Simple example
1 lb/imp gal × 0.02360591605 = 0.0236059161 kg/cup
1 pound per imperial gallon = 0.0236059161 kilograms per cup.
Real-world example
1,000 lb/imp gal × 0.02360591605 = 23.60591605 kg/cup
1,000 pounds per imperial gallon = 23.60591605 kilograms per cup.
