About Converting Drams per Milliliter to Carats per Teaspoon
Dram 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 = drams per milliliter × 43.6664302198
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per milliliter equals 1771.84519531 base units, and 1 carat per teaspoon equals 40.5768272422 base units, so dividing one by the other gives the direct dram per milliliter-to-carat per teaspoon factor of 43.6664302198.
Simple example
1 dr/mL × 43.66643022 = 43.66643022 ct/tsp
1 dram per milliliter = 43.66643022 carats per teaspoon.
Real-world example
1,000 dr/mL × 43.66643022 = 43,666.43022 ct/tsp
1,000 drams per milliliter = 43,666.43022 carats per teaspoon.

Frequently asked questions
How many carats per teaspoon are in 1 dram per milliliter?
1 dram per milliliter equals 43.66643022 carats per teaspoon, using the exact defined conversion factor rather than an estimate.
How do I convert dram per milliliter to carat per teaspoon?
Multiply the dram per milliliter value by 43.66643022. The converter above does this instantly to whatever precision you set.
How do I convert carat per teaspoon back to dram per milliliter?
Use the reverse factor: 1 carat per teaspoon equals 0.0229008874 drams per milliliter. You can also use the swap control in the converter above to flip the direction instantly.
What is a dram per milliliter?
Dram per Milliliter (dr/mL) 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 milliliter to carat per teaspoon conversion exact?
Yes. Both dram per milliliter and carat per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 43.66643022 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.
