About Converting Ounces per Cubic foot to Pounds per Imperial gallon
Ounce per Cubic foot and Pound per Imperial 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 imperial gallon = ounces per cubic foot × 0.0100339783272
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per cubic foot equals 1.00115396087 base units, and 1 pound per imperial gallon equals 99.7763726631 base units, so dividing one by the other gives the direct ounce per cubic foot-to-pound per imperial gallon factor of 0.0100339783272.
