About Converting Ounces per Cubic foot to Grains per Imperial gallon
Ounce per Cubic foot and Grain 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
grains per imperial gallon = ounces per cubic foot × 70.2378482907
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 grain per imperial gallon equals 0.0142537675233 base units, so dividing one by the other gives the direct ounce per cubic foot-to-grain per imperial gallon factor of 70.2378482907.
Simple example
1 oz/ft3 × 70.23784829 = 70.23784829 gr/imp gal
1 ounce per cubic foot = 70.23784829 grains per imperial gallon.
