About Converting Grains per Milliliter to Drams per Imperial gallon
Grain per Milliliter 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 = grains per milliliter × 166.257005714
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per milliliter equals 64.79891 base units, and 1 dram per imperial gallon equals 0.389751455715 base units, so dividing one by the other gives the direct grain per milliliter-to-dram per imperial gallon factor of 166.257005714.
Simple example
1 gr/mL × 166.2570057 = 166.2570057 dr/imp gal
1 grain per milliliter = 166.2570057 drams per imperial gallon.
Real-world example
1,000 gr/mL × 166.2570057 = 166,257.0057 dr/imp gal
1,000 grains per milliliter = 166,257.0057 drams per imperial gallon.

Frequently asked questions
How many drams per imperial gallon are in 1 grain per milliliter?
1 grain per milliliter equals 166.2570057 drams per imperial gallon, using the exact defined conversion factor rather than an estimate.
How do I convert grain per milliliter to dram per imperial gallon?
Multiply the grain per milliliter value by 166.2570057. The converter above does this instantly to whatever precision you set.
How do I convert dram per imperial gallon back to grain per milliliter?
Use the reverse factor: 1 dram per imperial gallon equals 0.0060147841 grains per milliliter. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per milliliter?
Grain per Milliliter (gr/mL) 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 grain per milliliter to dram per imperial gallon conversion exact?
Yes. Both grain per milliliter and dram per imperial gallon are defined by fixed standards rather than physical artifacts, so the factor of 166.2570057 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.
