About Converting Grains per Cubic foot to Pounds per Imperial gallon
Grain 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 = grains per cubic foot × 0.0000229348076051
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per cubic foot equals 0.00228835191057 base units, and 1 pound per imperial gallon equals 99.7763726631 base units, so dividing one by the other gives the direct grain per cubic foot-to-pound per imperial gallon factor of 0.0000229348076051.
Simple example
1 gr/ft3 × 0.00002293480761 = 0.0000229348 lb/imp gal
1 grain per cubic foot = 0.0000229348 pounds per imperial gallon.
Real-world example
1,000 gr/ft3 × 0.00002293480761 = 0.0229348076 lb/imp gal
1,000 grains per cubic foot = 0.0229348076 pounds per imperial gallon.
