About Converting Troy ounces per Fluid ounce to Stones per Milliliter
Troy ounce per Fluid ounce and Stone per Milliliter 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
stones per milliliter = troy ounces per fluid ounce × 0.000165619703029
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 stone per milliliter equals 6350293.18 base units, so dividing one by the other gives the direct troy ounce per fluid ounce-to-stone per milliliter factor of 0.000165619703029.
Simple example
1 oz t/fl oz × 0.000165619703 = 0.0001656197 st/mL
1 troy ounce per fluid ounce = 0.0001656197 stones per milliliter.
Real-world example
1,000 oz t/fl oz × 0.000165619703 = 0.165619703 st/mL
1,000 troy ounces per fluid ounce = 0.165619703 stones per milliliter.

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 stone per milliliter?
Stone per Milliliter (st/mL) is a unit of density.
Is the troy ounce per fluid ounce to stone per milliliter conversion exact?
Yes. Both troy ounce per fluid ounce and stone per milliliter are defined by fixed standards rather than physical artifacts, so the factor of 0.000165619703 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.
