About Converting Carats per Milliliter to Carats per Teaspoon
Carat per Milliliter and Carat per Teaspoon 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 teaspoon = carats per milliliter × 4.92892159375
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 teaspoon equals 40.5768272422 base units, so dividing one by the other gives the direct carat per milliliter-to-carat per teaspoon factor of 4.92892159375.
Simple example
1 ct/mL × 4.928921594 = 4.928921594 ct/tsp
1 carat per milliliter = 4.928921594 carats per teaspoon.
Real-world example
1,000 ct/mL × 4.928921594 = 4,928.921594 ct/tsp
1,000 carats per milliliter = 4,928.921594 carats per teaspoon.

Frequently asked questions
How many carats per teaspoon are in 1 carat per milliliter?
1 carat per milliliter equals 4.928921594 carats per teaspoon, using the exact defined conversion factor rather than an estimate.
How do I convert carat per milliliter to carat per teaspoon?
Multiply the carat per milliliter value by 4.928921594. The converter above does this instantly to whatever precision you set.
How do I convert carat per teaspoon back to carat per milliliter?
Use the reverse factor: 1 carat per teaspoon equals 0.2028841362 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 teaspoon?
Carat per Teaspoon (ct/tsp) is a unit of density.
Is the carat per milliliter to carat per teaspoon conversion exact?
Yes. Both carat per milliliter and carat per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 4.928921594 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.
