About Converting Carats per Milliliter to Centigrams per Milliliter
Carat per Milliliter and Centigram 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
centigrams per milliliter = carats per milliliter × 20
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 centigram per milliliter equals 10 base units, so dividing one by the other gives the direct carat per milliliter-to-centigram per milliliter factor of 20.
Simple example
1 ct/mL × 20 = 20 cg/mL
1 carat per milliliter = 20 centigrams per milliliter.
Real-world example
1,000 ct/mL × 20 = 20,000 cg/mL
1,000 carats per milliliter = 20,000 centigrams per milliliter.

Frequently asked questions
How many centigrams per milliliter are in 1 carat per milliliter?
1 carat per milliliter equals 20 centigrams per milliliter, using the exact defined conversion factor rather than an estimate.
How do I convert carat per milliliter to centigram per milliliter?
Multiply the carat per milliliter value by 20. The converter above does this instantly to whatever precision you set.
How do I convert centigram per milliliter back to carat per milliliter?
Use the reverse factor: 1 centigram per milliliter equals 0.05 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 centigram per milliliter?
Centigram per Milliliter (cg/mL) is a unit of density.
Is the carat per milliliter to centigram per milliliter conversion exact?
Yes. Both carat per milliliter and centigram per milliliter are defined by fixed standards rather than physical artifacts, so the factor of 20 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.
