About Converting Drams per Liter to Long tons per Imperial gallon
Dram per Liter 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 liter × 0.00000792775181362
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per liter equals 1.77184519531 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 liter-to-long ton per imperial gallon factor of 0.00000792775181362.
Simple example
1 dr/L × 0.000007927751814 = 0.0000079278 long ton/imp gal
1 dram per liter = 0.0000079278 long tons per imperial gallon.
Real-world example
1,000 dr/L × 0.000007927751814 = 0.0079277518 long ton/imp gal
1,000 drams per liter = 0.0079277518 long tons per imperial gallon.

What is a dram per liter?
Dram per Liter (dr/L) is a unit of density.
What is a long ton per imperial gallon?
Long ton per Imperial gallon (long ton/imp gal) is a unit of density.
Is the dram per liter to long ton per imperial gallon conversion exact?
Yes. Both dram per liter and long ton per imperial gallon are defined by fixed standards rather than physical artifacts, so the factor of 0.000007927751814 used above is exact to as many digits as you choose to display.
What's the difference between density and mass concentration?
Density is the mass of a pure substance or material per unit volume. Mass concentration is the mass of one component — like a dissolved solute — within a mixture's total volume. The two use the same kind of units but describe different physical situations.
