About Converting Carats per Teaspoon to Decigrams per Cubic Millimeter
Carat per Teaspoon and Decigram 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
decigrams per cubic millimeter = carats per teaspoon × 0.000405768272422
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 decigram per cubic millimeter equals 100000 base units, so dividing one by the other gives the direct carat per teaspoon-to-decigram per cubic millimeter factor of 0.000405768272422.
Simple example
1 ct/tsp × 0.0004057682724 = 0.0004057683 dg/mm3
1 carat per teaspoon = 0.0004057683 decigrams per cubic millimeter.
Real-world example
1,000 ct/tsp × 0.0004057682724 = 0.4057682724 dg/mm3
1,000 carats per teaspoon = 0.4057682724 decigrams per cubic millimeter.

Frequently asked questions
How many decigrams per cubic millimeter are in 1 carat per teaspoon?
1 carat per teaspoon equals 0.0004057683 decigrams per cubic millimeter, using the exact defined conversion factor rather than an estimate.
How do I convert carat per teaspoon to decigram per cubic millimeter?
Multiply the carat per teaspoon value by 0.0004057682724. The converter above does this instantly to whatever precision you set.
How do I convert decigram per cubic millimeter back to carat per teaspoon?
Use the reverse factor: 1 decigram per cubic millimeter equals 2,464.460797 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 decigram per cubic millimeter?
Decigram per Cubic Millimeter (dg/mm3) is a unit of density.
Is the carat per teaspoon to decigram per cubic millimeter conversion exact?
Yes. Both carat per teaspoon and decigram per cubic millimeter are defined by fixed standards rather than physical artifacts, so the factor of 0.0004057682724 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.
