About Converting Pounds per Imperial gallon to Long tons per Cubic Centimeter
Pound per Imperial gallon and Long ton per Cubic Centimeter 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 centimeter = pounds per imperial gallon × 9.820056e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per imperial gallon equals 99.7763726631 base units, and 1 long ton per cubic centimeter equals 1016046908.8 base units, so dividing one by the other gives the direct pound per imperial gallon-to-long ton per cubic centimeter factor of 9.820056e-8.
Simple example
1 lb/imp gal × 9.820056e-8 = 9.820056e-8 long ton/cm3
1 pound per imperial gallon = 9.820056e-8 long tons per cubic centimeter.
Real-world example
1,000 lb/imp gal × 9.820056e-8 = 0.0000982006 long ton/cm3
1,000 pounds per imperial gallon = 0.0000982006 long tons per cubic centimeter.
