About Converting US hundredweights per Cup to Pounds per Gallon
US hundredweight per Cup 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 cup × 1600
This factor comes from each unit's defined relationship to the category's base unit: 1 us hundredweight per cup equals 191722.283707 base units, and 1 pound per gallon equals 119.826427317 base units, so dividing one by the other gives the direct us hundredweight per cup-to-pound per gallon factor of 1600.
Simple example
1 cwt/cup × 1600 = 1,600 lb/gal
1 us hundredweight per cup = 1,600 pounds per gallon.
Real-world example
1,000 cwt/cup × 1600 = 1,600,000 lb/gal
1,000 us hundredweights per cup = 1,600,000 pounds per gallon.

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.
