About Converting Grains per Tablespoon to US hundredweights per Gallon
Grain per Tablespoon 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 tablespoon × 0.000365714285714
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per tablespoon equals 4.38222362759 base units, and 1 us hundredweight per gallon equals 11982.6427317 base units, so dividing one by the other gives the direct grain per tablespoon-to-us hundredweight per gallon factor of 0.000365714285714.
