About Converting Drams per Quart to Milligrams per Fluid ounce
Dram per Quart and Milligram per Fluid ounce 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 fluid ounce = drams per quart × 55.3701623535
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per quart equals 1.87228792683 base units, and 1 milligram per fluid ounce equals 0.0338140227018 base units, so dividing one by the other gives the direct dram per quart-to-milligram per fluid ounce factor of 55.3701623535.
Simple example
1 dr/qt × 55.37016235 = 55.37016235 mg/fl oz
1 dram per quart = 55.37016235 milligrams per fluid ounce.
Real-world example
1,000 dr/qt × 55.37016235 = 55,370.16235 mg/fl oz
1,000 drams per quart = 55,370.16235 milligrams per fluid ounce.

What is a dram per quart?
Dram per Quart (dr/qt) is a unit of density.
What is a milligram per fluid ounce?
Milligram per Fluid ounce (mg/fl oz) is a unit of density.
Is the dram per quart to milligram per fluid ounce conversion exact?
Yes. Both dram per quart and milligram per fluid ounce are defined by fixed standards rather than physical artifacts, so the factor of 55.37016235 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.
