About Converting Carats per Teaspoon to Decigrams per Milliliter
Carat per Teaspoon and Decigram per Milliliter 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 milliliter = carats per teaspoon × 0.405768272422
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 milliliter equals 100 base units, so dividing one by the other gives the direct carat per teaspoon-to-decigram per milliliter factor of 0.405768272422.
Simple example
1 ct/tsp × 0.4057682724 = 0.4057682724 dg/mL
1 carat per teaspoon = 0.4057682724 decigrams per milliliter.
Real-world example
1,000 ct/tsp × 0.4057682724 = 405.7682724 dg/mL
1,000 carats per teaspoon = 405.7682724 decigrams per milliliter.

Frequently asked questions
How many decigrams per milliliter are in 1 carat per teaspoon?
1 carat per teaspoon equals 0.4057682724 decigrams per milliliter, using the exact defined conversion factor rather than an estimate.
How do I convert carat per teaspoon to decigram per milliliter?
Multiply the carat per teaspoon value by 0.4057682724. The converter above does this instantly to whatever precision you set.
How do I convert decigram per milliliter back to carat per teaspoon?
Use the reverse factor: 1 decigram per milliliter equals 2.464460797 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 milliliter?
Decigram per Milliliter (dg/mL) is a unit of density.
Is the carat per teaspoon to decigram per milliliter conversion exact?
Yes. Both carat per teaspoon and decigram per milliliter are defined by fixed standards rather than physical artifacts, so the factor of 0.4057682724 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.
