About Converting Pounds per Imperial gallon to Carats per Quart
Pound per Imperial gallon and Carat per Quart 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
carats per quart = pounds per imperial gallon × 472.118321055
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 carat per quart equals 0.211337641887 base units, so dividing one by the other gives the direct pound per imperial gallon-to-carat per quart factor of 472.118321055.
Simple example
1 lb/imp gal × 472.1183211 = 472.1183211 ct/qt
1 pound per imperial gallon = 472.1183211 carats per quart.
Real-world example
1,000 lb/imp gal × 472.1183211 = 472,118.3211 ct/qt
