About Converting Milligrams per Tablespoon to Drams per Imperial gallon
Milligram per Tablespoon and Dram 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
drams per imperial gallon = milligrams per tablespoon × 0.173515825052
This factor comes from each unit's defined relationship to the category's base unit: 1 milligram per tablespoon equals 0.0676280454037 base units, and 1 dram per imperial gallon equals 0.389751455715 base units, so dividing one by the other gives the direct milligram per tablespoon-to-dram per imperial gallon factor of 0.173515825052.
Simple example
1 mg/tbsp × 0.1735158251 = 0.1735158251 dr/imp gal
1 milligram per tablespoon = 0.1735158251 drams per imperial gallon.
Real-world example
1,000 mg/tbsp × 0.1735158251 = 173.5158251 dr/imp gal
1,000 milligrams per tablespoon = 173.5158251 drams per imperial gallon.

What is a milligram per tablespoon?
Milligram per Tablespoon (mg/tbsp) is a unit of density.
What is a dram per imperial gallon?
Dram per Imperial gallon (dr/imp gal) is a unit of density.
Is the milligram per tablespoon to dram per imperial gallon conversion exact?
Yes. Both milligram per tablespoon and dram per imperial gallon are defined by fixed standards rather than physical artifacts, so the factor of 0.1735158251 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.
