About Converting Grain per Cubic inches to US hundredweights per Imperial gallon
Grain per Cubic inch and US hundredweight 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
us hundredweights per imperial gallon = grain per cubic inches × 0.000396313475417
