About Converting Drams per Teaspoon to Hectograms per Imperial gallon
Dram per Teaspoon and Hectogram 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
hectograms per imperial gallon = drams per teaspoon × 16.3422516888
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per teaspoon equals 359.479281951 base units, and 1 hectogram per imperial gallon equals 21.9969248299 base units, so dividing one by the other gives the direct dram per teaspoon-to-hectogram per imperial gallon factor of 16.3422516888.
Simple example
1 dr/tsp × 16.34225169 = 16.34225169 hg/imp gal
1 dram per teaspoon = 16.34225169 hectograms per imperial gallon.
Real-world example
1,000 dr/tsp × 16.34225169 = 16,342.25169 hg/imp gal
1,000 drams per teaspoon = 16,342.25169 hectograms per imperial gallon.

Frequently asked questions
How many hectograms per imperial gallon are in 1 dram per teaspoon?
1 dram per teaspoon equals 16.34225169 hectograms per imperial gallon, using the exact defined conversion factor rather than an estimate.
How do I convert dram per teaspoon to hectogram per imperial gallon?
Multiply the dram per teaspoon value by 16.34225169. The converter above does this instantly to whatever precision you set.
How do I convert hectogram per imperial gallon back to dram per teaspoon?
Use the reverse factor: 1 hectogram per imperial gallon equals 0.0611910781 drams per teaspoon. You can also use the swap control in the converter above to flip the direction instantly.
What is a dram per teaspoon?
Dram per Teaspoon (dr/tsp) is a unit of density.
What is a hectogram per imperial gallon?
Hectogram per Imperial gallon (hg/imp gal) is a unit of density.
Is the dram per teaspoon to hectogram per imperial gallon conversion exact?
Yes. Both dram per teaspoon and hectogram per imperial gallon are defined by fixed standards rather than physical artifacts, so the factor of 16.34225169 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.
