About Converting US hundredweights per Cubic Meter to Pounds per Gallon
US hundredweight per Cubic Meter and Pound per Gallon 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 gallon = us hundredweights per cubic meter × 0.3785411784
This factor comes from each unit's defined relationship to the category's base unit: 1 us hundredweight per cubic meter equals 45.359237 base units, and 1 pound per gallon equals 119.826427317 base units, so dividing one by the other gives the direct us hundredweight per cubic meter-to-pound per gallon factor of 0.3785411784.
Simple example
1 cwt/m3 × 0.3785411784 = 0.3785411784 lb/gal
1 us hundredweight per cubic meter = 0.3785411784 pounds per gallon.
Real-world example
1,000 cwt/m3 × 0.3785411784 = 378.5411784 lb/gal
1,000 us hundredweights per cubic meter = 378.5411784 pounds per gallon.

Understanding the US hundredweight per Cubic Meter (cwt/m3)
Mass per volume density.
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.
Uses of the Pound per Gallon today
- US paint and coatings density specifications
- US fuel and petroleum liquid density specs
