About Converting Troy ounces per Milliliter to Carats per Cubic Millimeter
Troy ounce per Milliliter and Carat 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
carats per cubic millimeter = troy ounces per milliliter × 0.155517384
This factor comes from each unit's defined relationship to the category's base unit: 1 troy ounce per milliliter equals 31103.4768 base units, and 1 carat per cubic millimeter equals 200000 base units, so dividing one by the other gives the direct troy ounce per milliliter-to-carat per cubic millimeter factor of 0.155517384.
Simple example
1 oz t/mL × 0.155517384 = 0.155517384 ct/mm3
1 troy ounce per milliliter = 0.155517384 carats per cubic millimeter.
Real-world example
1,000 oz t/mL × 0.155517384 = 155.517384 ct/mm3
1,000 troy ounces per milliliter = 155.517384 carats per cubic millimeter.

Frequently asked questions
How many carats per cubic millimeter are in 1 troy ounce per milliliter?
1 troy ounce per milliliter equals 0.155517384 carats per cubic millimeter, using the exact defined conversion factor rather than an estimate.
How do I convert troy ounce per milliliter to carat per cubic millimeter?
Multiply the troy ounce per milliliter value by 0.155517384. The converter above does this instantly to whatever precision you set.
How do I convert carat per cubic millimeter back to troy ounce per milliliter?
Use the reverse factor: 1 carat per cubic millimeter equals 6.430149314 troy ounces per milliliter. You can also use the swap control in the converter above to flip the direction instantly.
What is a troy ounce per milliliter?
Troy ounce per Milliliter (oz t/mL) is a unit of density.
What is a carat per cubic millimeter?
Carat per Cubic Millimeter (ct/mm3) is a unit of density.
Is the troy ounce per milliliter to carat per cubic millimeter conversion exact?
Yes. Both troy ounce per milliliter and carat per cubic millimeter are defined by fixed standards rather than physical artifacts, so the factor of 0.155517384 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.
