About Converting Grains per Cup to US hundredweights per Gallon
Grain per Cup and US hundredweight per 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 gallon = grains per cup × 0.0000228571428571
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per cup equals 0.273888976724 base units, and 1 us hundredweight per gallon equals 11982.6427317 base units, so dividing one by the other gives the direct grain per cup-to-us hundredweight per gallon factor of 0.0000228571428571.
Simple example
1 gr/cup × 0.00002285714286 = 0.0000228571 cwt/gal
1 grain per cup = 0.0000228571 us hundredweights per gallon.
Real-world example
1,000 gr/cup × 0.00002285714286 = 0.0228571429 cwt/gal
1,000 grains per cup = 0.0228571429 us hundredweights per gallon.
