About Converting Stones per Milliliter to Carats per Fluid ounce
Stone per Milliliter and Carat 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
carats per fluid ounce = stones per milliliter × 939002.915446
This factor comes from each unit's defined relationship to the category's base unit: 1 stone per milliliter equals 6350293.18 base units, and 1 carat per fluid ounce equals 6.76280454037 base units, so dividing one by the other gives the direct stone per milliliter-to-carat per fluid ounce factor of 939002.915446.
Simple example
1 st/mL × 939002.9154 = 939,002.9154 ct/fl oz
1 stone per milliliter = 939,002.9154 carats per fluid ounce.
Real-world example
1,000 st/mL × 939002.9154 = 939,002,915.4 ct/fl oz
1,000 stones per milliliter = 939,002,915.4 carats per fluid ounce.

Frequently asked questions
How many carats per fluid ounce are in 1 stone per milliliter?
1 stone per milliliter equals 939,002.9154 carats per fluid ounce, using the exact defined conversion factor rather than an estimate.
How do I convert stone per milliliter to carat per fluid ounce?
Multiply the stone per milliliter value by 939002.9154. The converter above does this instantly to whatever precision you set.
How do I convert carat per fluid ounce back to stone per milliliter?
Use the reverse factor: 1 carat per fluid ounce equals 0.000001065 stones per milliliter. You can also use the swap control in the converter above to flip the direction instantly.
What is a stone per milliliter?
Stone per Milliliter (st/mL) is a unit of density.
What is a carat per fluid ounce?
Carat per Fluid ounce (ct/fl oz) is a unit of density.
Is the stone per milliliter to carat per fluid ounce conversion exact?
Yes. Both stone per milliliter and carat per fluid ounce are defined by fixed standards rather than physical artifacts, so the factor of 939002.9154 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.
