About Converting Carats per Milliliter to Troy ounces per Cubic Millimeter
Carat per Milliliter and Troy ounce 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
troy ounces per cubic millimeter = carats per milliliter × 0.00000643014931373
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per milliliter equals 200 base units, and 1 troy ounce per cubic millimeter equals 31103476.8 base units, so dividing one by the other gives the direct carat per milliliter-to-troy ounce per cubic millimeter factor of 0.00000643014931373.
Simple example
1 ct/mL × 0.000006430149314 = 0.0000064301 oz t/mm3
1 carat per milliliter = 0.0000064301 troy ounces per cubic millimeter.
Real-world example
1,000 ct/mL × 0.000006430149314 = 0.0064301493 oz t/mm3
1,000 carats per milliliter = 0.0064301493 troy ounces per cubic millimeter.

Frequently asked questions
How many troy ounces per cubic millimeter are in 1 carat per milliliter?
1 carat per milliliter equals 0.0000064301 troy ounces per cubic millimeter, using the exact defined conversion factor rather than an estimate.
How do I convert carat per milliliter to troy ounce per cubic millimeter?
Multiply the carat per milliliter value by 0.000006430149314. The converter above does this instantly to whatever precision you set.
How do I convert troy ounce per cubic millimeter back to carat per milliliter?
Use the reverse factor: 1 troy ounce per cubic millimeter equals 155,517.384 carats per milliliter. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per milliliter?
Carat per Milliliter (ct/mL) is a unit of density.
What is a troy ounce per cubic millimeter?
Troy ounce per Cubic Millimeter (oz t/mm3) is a unit of density.
Is the carat per milliliter to troy ounce per cubic millimeter conversion exact?
Yes. Both carat per milliliter and troy ounce per cubic millimeter are defined by fixed standards rather than physical artifacts, so the factor of 0.000006430149314 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.
