About Converting Drams per Cubic Millimeter to Carats per Teaspoon
Dram per Cubic Millimeter 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 = drams per cubic millimeter × 43666.4302198
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per cubic millimeter equals 1771845.19531 base units, and 1 carat per teaspoon equals 40.5768272422 base units, so dividing one by the other gives the direct dram per cubic millimeter-to-carat per teaspoon factor of 43666.4302198.
Simple example
1 dr/mm3 × 43666.43022 = 43,666.43022 ct/tsp
1 dram per cubic millimeter = 43,666.43022 carats per teaspoon.
Real-world example
1,000 dr/mm3 × 43666.43022 = 43,666,430.22 ct/tsp
1,000 drams per cubic millimeter = 43,666,430.22 carats per teaspoon.

Frequently asked questions
How many carats per teaspoon are in 1 dram per cubic millimeter?
1 dram per cubic millimeter equals 43,666.43022 carats per teaspoon, using the exact defined conversion factor rather than an estimate.
How do I convert dram per cubic millimeter to carat per teaspoon?
Multiply the dram per cubic millimeter value by 43666.43022. The converter above does this instantly to whatever precision you set.
How do I convert carat per teaspoon back to dram per cubic millimeter?
Use the reverse factor: 1 carat per teaspoon equals 0.0000229009 drams per cubic millimeter. You can also use the swap control in the converter above to flip the direction instantly.
What is a dram per cubic millimeter?
Dram per Cubic Millimeter (dr/mm3) is a unit of density.
What is a carat per teaspoon?
Carat per Teaspoon (ct/tsp) is a unit of density.
Is the dram per cubic millimeter to carat per teaspoon conversion exact?
Yes. Both dram per cubic millimeter and carat per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 43666.43022 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.
