About Converting Pounds per Gallon to Imperial hundredweights per Cubic Meter
Pound per Gallon and Imperial hundredweight per Cubic Meter 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 cubic meter = pounds per gallon × 2.35867903891
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 cubic meter equals 50.80234544 base units, so dividing one by the other gives the direct pound per gallon-to-imperial hundredweight per cubic meter factor of 2.35867903891.
Simple example
1 lb/gal × 2.358679039 = 2.358679039 long cwt/m3
1 pound per gallon = 2.358679039 imperial hundredweights per cubic meter.
Real-world example
1,000 lb/gal × 2.358679039 = 2,358.679039 long cwt/m3
1,000 pounds per gallon = 2,358.679039 imperial hundredweights per cubic meter.

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.
