About Converting Carats per Cubic Millimeter to Drams per Teaspoon
Carat per Cubic Millimeter and Dram 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
drams per teaspoon = carats per cubic millimeter × 556.360296801
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per cubic millimeter equals 200000 base units, and 1 dram per teaspoon equals 359.479281951 base units, so dividing one by the other gives the direct carat per cubic millimeter-to-dram per teaspoon factor of 556.360296801.
Simple example
1 ct/mm3 × 556.3602968 = 556.3602968 dr/tsp
1 carat per cubic millimeter = 556.3602968 drams per teaspoon.
Real-world example
1,000 ct/mm3 × 556.3602968 = 556,360.2968 dr/tsp
1,000 carats per cubic millimeter = 556,360.2968 drams per teaspoon.

Frequently asked questions
How many drams per teaspoon are in 1 carat per cubic millimeter?
1 carat per cubic millimeter equals 556.3602968 drams per teaspoon, using the exact defined conversion factor rather than an estimate.
How do I convert carat per cubic millimeter to dram per teaspoon?
Multiply the carat per cubic millimeter value by 556.3602968. The converter above does this instantly to whatever precision you set.
How do I convert dram per teaspoon back to carat per cubic millimeter?
Use the reverse factor: 1 dram per teaspoon equals 0.0017973964 carats per cubic millimeter. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per cubic millimeter?
Carat per Cubic Millimeter (ct/mm3) is a unit of density.
What is a dram per teaspoon?
Dram per Teaspoon (dr/tsp) is a unit of density.
Is the carat per cubic millimeter to dram per teaspoon conversion exact?
Yes. Both carat per cubic millimeter and dram per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 556.3602968 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.
