About Converting Imperial hundredweights per Gallon to Pounds per Cubic foot
Imperial hundredweight per Gallon and Pound per Cubic foot 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 cubic foot = imperial hundredweights per gallon × 837.818181818
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial hundredweight per gallon equals 13420.5598595 base units, and 1 pound per cubic foot equals 16.018463374 base units, so dividing one by the other gives the direct imperial hundredweight per gallon-to-pound per cubic foot factor of 837.818181818.
Simple example
1 long cwt/gal × 837.8181818 = 837.8181818 lb/ft3
1 imperial hundredweight per gallon = 837.8181818 pounds per cubic foot.
Real-world example
1,000 long cwt/gal × 837.8181818 = 837,818.1818 lb/ft3
1,000 imperial hundredweights per gallon = 837,818.1818 pounds per cubic foot.
