About Converting Troy ounces per Fluid ounce to Drams per Cubic Millimeter
Troy ounce per Fluid ounce and Dram per Cubic Millimeter 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 cubic millimeter = troy ounces per fluid ounce × 0.000593581015657
This factor comes from each unit's defined relationship to the category's base unit: 1 troy ounce per fluid ounce equals 1051.73367062 base units, and 1 dram per cubic millimeter equals 1771845.19531 base units, so dividing one by the other gives the direct troy ounce per fluid ounce-to-dram per cubic millimeter factor of 0.000593581015657.
Simple example
1 oz t/fl oz × 0.0005935810157 = 0.000593581 dr/mm3
1 troy ounce per fluid ounce = 0.000593581 drams per cubic millimeter.
Real-world example
1,000 oz t/fl oz × 0.0005935810157 = 0.5935810157 dr/mm3
1,000 troy ounces per fluid ounce = 0.5935810157 drams per cubic millimeter.

What is a troy ounce per fluid ounce?
Troy ounce per Fluid ounce (oz t/fl oz) is a unit of density.
What is a dram per cubic millimeter?
Dram per Cubic Millimeter (dr/mm3) is a unit of density.
Is the troy ounce per fluid ounce to dram per cubic millimeter conversion exact?
Yes. Both troy ounce per fluid ounce and dram per cubic millimeter are defined by fixed standards rather than physical artifacts, so the factor of 0.0005935810157 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.
