About Converting Carats per Milliliter to Carat per Cubic inches
Carat per Milliliter and Carat per Cubic inch 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
carat per cubic inches = carats per milliliter × 16.387064
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 carat per cubic inch equals 12.2047488189 base units, so dividing one by the other gives the direct carat per milliliter-to-carat per cubic inch factor of 16.387064.
Simple example
1 ct/mL × 16.387064 = 16.387064 ct/in3
1 carat per milliliter = 16.387064 carat per cubic inches.
Real-world example
1,000 ct/mL × 16.387064 = 16,387.064 ct/in3
1,000 carats per milliliter = 16,387.064 carat per cubic inches.

Frequently asked questions
How many carat per cubic inches are in 1 carat per milliliter?
1 carat per milliliter equals 16.387064 carat per cubic inches, using the exact defined conversion factor rather than an estimate.
How do I convert carat per milliliter to carat per cubic inch?
Multiply the carat per milliliter value by 16.387064. The converter above does this instantly to whatever precision you set.
How do I convert carat per cubic inch back to carat per milliliter?
Use the reverse factor: 1 carat per cubic inch equals 0.0610237441 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 carat per cubic inch?
Carat per Cubic inch (ct/in3) is a unit of density.
Is the carat per milliliter to carat per cubic inch conversion exact?
Yes. Both carat per milliliter and carat per cubic inch are defined by fixed standards rather than physical artifacts, so the factor of 16.387064 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.
