About Converting Drams per Liter to Long tons per Gallon
Dram per Liter and Long ton per 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 gallon = drams per liter × 0.00000660123427734
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 gallon equals 268411.19719 base units, so dividing one by the other gives the direct dram per liter-to-long ton per gallon factor of 0.00000660123427734.
Simple example
1 dr/L × 0.000006601234277 = 0.0000066012 long ton/gal
1 dram per liter = 0.0000066012 long tons per gallon.
Real-world example
1,000 dr/L × 0.000006601234277 = 0.0066012343 long ton/gal
1,000 drams per liter = 0.0066012343 long tons per gallon.

What is a dram per liter?
Dram per Liter (dr/L) is a unit of density.
What is a long ton per gallon?
Long ton per Gallon (long ton/gal) is a unit of density.
Is the dram per liter to long ton per gallon conversion exact?
Yes. Both dram per liter and long ton per gallon are defined by fixed standards rather than physical artifacts, so the factor of 0.000006601234277 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.
