About Converting Pounds per Imperial gallon to Milligrams per Cup
Pound per Imperial gallon and Milligram 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
milligrams per cup = pounds per imperial gallon × 23605.9160527
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 milligram per cup equals 0.00422675283773 base units, so dividing one by the other gives the direct pound per imperial gallon-to-milligram per cup factor of 23605.9160527.
Simple example
1 lb/imp gal × 23605.91605 = 23,605.91605 mg/cup
1 pound per imperial gallon = 23,605.91605 milligrams per cup.
Real-world example
1,000 lb/imp gal × 23605.91605 = 23,605,916.05 mg/cup
1,000 pounds per imperial gallon = 23,605,916.05 milligrams per cup.
