About Converting Drams per Milliliter to Pounds per Imperial gallon
Dram per Milliliter and Pound 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
pounds per imperial gallon = drams per milliliter × 17.7581640625
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per milliliter equals 1771.84519531 base units, and 1 pound per imperial gallon equals 99.7763726631 base units, so dividing one by the other gives the direct dram per milliliter-to-pound per imperial gallon factor of 17.7581640625.
Simple example
1 dr/mL × 17.75816406 = 17.75816406 lb/imp gal
1 dram per milliliter = 17.75816406 pounds per imperial gallon.
Real-world example
1,000 dr/mL × 17.75816406 = 17,758.16406 lb/imp gal
1,000 drams per milliliter = 17,758.16406 pounds per imperial gallon.

What is a dram per milliliter?
Dram per Milliliter (dr/mL) is a unit of density.
What is a pound per imperial gallon?
Pound per Imperial gallon (lb/imp gal) is a unit of density.
Is the dram per milliliter to pound per imperial gallon conversion exact?
Yes. Both dram per milliliter and pound per imperial gallon are defined by fixed standards rather than physical artifacts, so the factor of 17.75816406 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.
