About Converting Pounds per Imperial gallon to Long tons per Cubic Meter
Pound per Imperial gallon and Long ton per Cubic Meter 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 meter = pounds per imperial gallon × 0.0982005572764
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 meter equals 1016.0469088 base units, so dividing one by the other gives the direct pound per imperial gallon-to-long ton per cubic meter factor of 0.0982005572764.
Simple example
1 lb/imp gal × 0.09820055728 = 0.0982005573 long ton/m3
1 pound per imperial gallon = 0.0982005573 long tons per cubic meter.
Real-world example
1,000 lb/imp gal × 0.09820055728 = 98.20055728 long ton/m3
1,000 pounds per imperial gallon = 98.20055728 long tons per cubic meter.
