About Converting Carats per Fluid ounce to Stones per Milliliter
Carat 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 = carats per fluid ounce × 0.00000106495941977
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per fluid ounce equals 6.76280454037 base units, and 1 stone per milliliter equals 6350293.18 base units, so dividing one by the other gives the direct carat per fluid ounce-to-stone per milliliter factor of 0.00000106495941977.
Simple example
1 ct/fl oz × 0.00000106495942 = 0.000001065 st/mL
1 carat per fluid ounce = 0.000001065 stones per milliliter.
Real-world example
1,000 ct/fl oz × 0.00000106495942 = 0.0010649594 st/mL
1,000 carats per fluid ounce = 0.0010649594 stones per milliliter.

Frequently asked questions
How many stones per milliliter are in 1 carat per fluid ounce?
1 carat per fluid ounce equals 0.000001065 stones per milliliter, using the exact defined conversion factor rather than an estimate.
How do I convert carat per fluid ounce to stone per milliliter?
Multiply the carat per fluid ounce value by 0.00000106495942. The converter above does this instantly to whatever precision you set.
How do I convert stone per milliliter back to carat per fluid ounce?
Use the reverse factor: 1 stone per milliliter equals 939,002.9154 carats per fluid ounce. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per fluid ounce?
Carat per Fluid ounce (ct/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 carat per fluid ounce to stone per milliliter conversion exact?
Yes. Both carat per fluid ounce and stone per milliliter are defined by fixed standards rather than physical artifacts, so the factor of 0.00000106495942 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.
