About Converting US hundredweights per Imperial gallon to Long tons per Cubic Millimeter
US hundredweight per Imperial gallon and Long ton per Cubic Millimeter 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
long tons per cubic millimeter = us hundredweights per imperial gallon × 9.820056e-9
This factor comes from each unit's defined relationship to the category's base unit: 1 us hundredweight per imperial gallon equals 9977.63726631 base units, and 1 long ton per cubic millimeter equals 1.016047e+12 base units, so dividing one by the other gives the direct us hundredweight per imperial gallon-to-long ton per cubic millimeter factor of 9.820056e-9.
Simple example
1 cwt/imp gal × 9.820056e-9 = 9.820056e-9 long ton/mm3
1 us hundredweight per imperial gallon = 9.820056e-9 long tons per cubic millimeter.
Real-world example
1,000 cwt/imp gal × 9.820056e-9 = 0.0000098201 long ton/mm3
1,000 us hundredweights per imperial gallon = 0.0000098201 long tons per cubic millimeter.
