About Converting Troy ounces per Cup to Ounces per Imperial gallon
Troy ounce per Cup 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 = troy ounces per cup × 21.0818181209
This factor comes from each unit's defined relationship to the category's base unit: 1 troy ounce per cup equals 131.466708828 base units, and 1 ounce per imperial gallon equals 6.23602329144 base units, so dividing one by the other gives the direct troy ounce per cup-to-ounce per imperial gallon factor of 21.0818181209.
