About Converting Carats per Tablespoon to Decigrams per Teaspoon
Carat per Tablespoon and Decigram 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
decigrams per teaspoon = carats per tablespoon × 0.666666666667
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per tablespoon equals 13.5256090807 base units, and 1 decigram per teaspoon equals 20.2884136211 base units, so dividing one by the other gives the direct carat per tablespoon-to-decigram per teaspoon factor of 0.666666666667.
Simple example
1 ct/tbsp × 0.6666666667 = 0.6666666667 dg/tsp
1 carat per tablespoon = 0.6666666667 decigrams per teaspoon.
Real-world example
1,000 ct/tbsp × 0.6666666667 = 666.6666667 dg/tsp
1,000 carats per tablespoon = 666.6666667 decigrams per teaspoon.

Frequently asked questions
How many decigrams per teaspoon are in 1 carat per tablespoon?
1 carat per tablespoon equals 0.6666666667 decigrams per teaspoon, using the exact defined conversion factor rather than an estimate.
How do I convert carat per tablespoon to decigram per teaspoon?
Multiply the carat per tablespoon value by 0.6666666667. The converter above does this instantly to whatever precision you set.
How do I convert decigram per teaspoon back to carat per tablespoon?
Use the reverse factor: 1 decigram per teaspoon equals 1.5 carats per tablespoon. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per tablespoon?
Carat per Tablespoon (ct/tbsp) is a unit of density.
What is a decigram per teaspoon?
Decigram per Teaspoon (dg/tsp) is a unit of density.
Is the carat per tablespoon to decigram per teaspoon conversion exact?
Yes. Both carat per tablespoon and decigram per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 0.6666666667 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.
