About Converting Drams per Imperial gallon to Slugs per Teaspoon
Dram per Imperial gallon and Slug per Teaspoon 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
slugs per teaspoon = drams per imperial gallon × 1.31634e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per imperial gallon equals 0.389751455715 base units, and 1 slug per teaspoon equals 2960871.39136 base units, so dividing one by the other gives the direct dram per imperial gallon-to-slug per teaspoon factor of 1.31634e-7.
Simple example
1 dr/imp gal × 1.31634e-7 = 1.31634e-7 slug/tsp
1 dram per imperial gallon = 1.31634e-7 slugs per teaspoon.
Real-world example
1,000 dr/imp gal × 1.31634e-7 = 0.000131634 slug/tsp
1,000 drams per imperial gallon = 0.000131634 slugs per teaspoon.

What is a dram per imperial gallon?
Dram per Imperial gallon (dr/imp gal) is a unit of density.
What is a slug per teaspoon?
Slug per Teaspoon (slug/tsp) is a unit of density.
Is the dram per imperial gallon to slug per teaspoon conversion exact?
Yes. Both dram per imperial gallon and slug per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 1.31634e-7 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.
