About Converting Drams per Cubic foot to Long tons per Imperial gallon
Dram per Cubic foot and Long ton per Imperial 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
long tons per imperial gallon = drams per cubic foot × 2.799659e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per cubic foot equals 0.0625721225545 base units, and 1 long ton per imperial gallon equals 223499.074765 base units, so dividing one by the other gives the direct dram per cubic foot-to-long ton per imperial gallon factor of 2.799659e-7.
Simple example
1 dr/ft3 × 2.799659e-7 = 2.799659e-7 long ton/imp gal
1 dram per cubic foot = 2.799659e-7 long tons per imperial gallon.
Real-world example
1,000 dr/ft3 × 2.799659e-7 = 0.0002799659 long ton/imp gal
1,000 drams per cubic foot = 0.0002799659 long tons per imperial gallon.
