About Converting Pounds per Gallon to Imperial hundredweights per Quart
Pound per Gallon and Imperial hundredweight 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. Pound per Gallon is most often used for us paint and coatings density specifications.
Formula
imperial hundredweights per quart = pounds per gallon × 0.00223214285714
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per gallon equals 119.826427317 base units, and 1 imperial hundredweight per quart equals 53682.239438 base units, so dividing one by the other gives the direct pound per gallon-to-imperial hundredweight per quart factor of 0.00223214285714.
Simple example
1 lb/gal × 0.002232142857 = 0.0022321429 long cwt/qt
1 pound per gallon = 0.0022321429 imperial hundredweights per quart.
Real-world example
1,000 lb/gal × 0.002232142857 = 2.232142857 long cwt/qt
1,000 pounds per gallon = 2.232142857 imperial hundredweights per quart.

Understanding the Pound per Gallon
Pound per Gallon (lb/gal) measures density. The US customary unit for liquid density, based on the US gallon (231 cubic inches). It is classified as a US customary density unit.
Where it's used: United States (paint, fuel, and industrial liquid density specifications)
lb/gal vs. lb/ft³. Both are US customary density units; they're related through the real, fixed relationship between the US gallon and the cubic foot (1 cubic foot ≈ 7.48 US gallons), not a round conversion factor.
