About Converting Drams per Cup to Milligrams per Imperial gallon
Dram per Cup and Milligram 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
milligrams per imperial gallon = drams per cup × 34046.3576851
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per cup equals 7.48915170731 base units, and 1 milligram per imperial gallon equals 0.000219969248299 base units, so dividing one by the other gives the direct dram per cup-to-milligram per imperial gallon factor of 34046.3576851.
Simple example
1 dr/cup × 34046.35769 = 34,046.35769 mg/imp gal
1 dram per cup = 34,046.35769 milligrams per imperial gallon.
Real-world example
1,000 dr/cup × 34046.35769 = 34,046,357.69 mg/imp gal
1,000 drams per cup = 34,046,357.69 milligrams per imperial gallon.

What is a dram per cup?
Dram per Cup (dr/cup) is a unit of density.
What is a milligram per imperial gallon?
Milligram per Imperial gallon (mg/imp gal) is a unit of density.
Is the dram per cup to milligram per imperial gallon conversion exact?
Yes. Both dram per cup and milligram per imperial gallon are defined by fixed standards rather than physical artifacts, so the factor of 34046.35769 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.
