About Converting Carats per Teaspoon to Centigrams per Cubic Millimeter
Carat per Teaspoon and Centigram 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
centigrams per cubic millimeter = carats per teaspoon × 0.00405768272422
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per teaspoon equals 40.5768272422 base units, and 1 centigram per cubic millimeter equals 10000 base units, so dividing one by the other gives the direct carat per teaspoon-to-centigram per cubic millimeter factor of 0.00405768272422.
Simple example
1 ct/tsp × 0.004057682724 = 0.0040576827 cg/mm3
1 carat per teaspoon = 0.0040576827 centigrams per cubic millimeter.
Real-world example
1,000 ct/tsp × 0.004057682724 = 4.057682724 cg/mm3
1,000 carats per teaspoon = 4.057682724 centigrams per cubic millimeter.

Frequently asked questions
How many centigrams per cubic millimeter are in 1 carat per teaspoon?
1 carat per teaspoon equals 0.0040576827 centigrams per cubic millimeter, using the exact defined conversion factor rather than an estimate.
How do I convert carat per teaspoon to centigram per cubic millimeter?
Multiply the carat per teaspoon value by 0.004057682724. The converter above does this instantly to whatever precision you set.
How do I convert centigram per cubic millimeter back to carat per teaspoon?
Use the reverse factor: 1 centigram per cubic millimeter equals 246.4460797 carats per teaspoon. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per teaspoon?
Carat per Teaspoon (ct/tsp) is a unit of density.
What is a centigram per cubic millimeter?
Centigram per Cubic Millimeter (cg/mm3) is a unit of density.
Is the carat per teaspoon to centigram per cubic millimeter conversion exact?
Yes. Both carat per teaspoon and centigram per cubic millimeter are defined by fixed standards rather than physical artifacts, so the factor of 0.004057682724 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.
