About Converting Ounces per Fluid ounce to Ounces per Imperial gallon
Ounce per Fluid ounce and Ounce 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
ounces per imperial gallon = ounces per fluid ounce × 153.721590465
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per fluid ounce equals 958.611418535 base units, and 1 ounce per imperial gallon equals 6.23602329144 base units, so dividing one by the other gives the direct ounce per fluid ounce-to-ounce per imperial gallon factor of 153.721590465.
