About Converting Picograms per Imperial gallon to Pounds per Cup
Picogram 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 = picograms per imperial gallon × 1.147333e-16
This factor comes from each unit's defined relationship to the category's base unit: 1 picogram per imperial gallon equals 2.199692e-13 base units, and 1 pound per cup equals 1917.22283707 base units, so dividing one by the other gives the direct picogram per imperial gallon-to-pound per cup factor of 1.147333e-16.
Simple example
1 pg/imp gal × 1.147333e-16 = 1.147333e-16 lb/cup
1 picogram per imperial gallon = 1.147333e-16 pounds per cup.
Real-world example
1,000 pg/imp gal × 1.147333e-16 = 1.147333e-13 lb/cup
1,000 picograms per imperial gallon = 1.147333e-13 pounds per cup.
