About Converting Carats per Tablespoon to Milligrams per Teaspoon
Carat per Tablespoon and Milligram 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
milligrams per teaspoon = carats per tablespoon × 66.6666666667
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 milligram per teaspoon equals 0.202884136211 base units, so dividing one by the other gives the direct carat per tablespoon-to-milligram per teaspoon factor of 66.6666666667.
Simple example
1 ct/tbsp × 66.66666667 = 66.66666667 mg/tsp
1 carat per tablespoon = 66.66666667 milligrams per teaspoon.
Real-world example
1,000 ct/tbsp × 66.66666667 = 66,666.66667 mg/tsp
1,000 carats per tablespoon = 66,666.66667 milligrams per teaspoon.

Frequently asked questions
How many milligrams per teaspoon are in 1 carat per tablespoon?
1 carat per tablespoon equals 66.66666667 milligrams per teaspoon, using the exact defined conversion factor rather than an estimate.
How do I convert carat per tablespoon to milligram per teaspoon?
Multiply the carat per tablespoon value by 66.66666667. The converter above does this instantly to whatever precision you set.
How do I convert milligram per teaspoon back to carat per tablespoon?
Use the reverse factor: 1 milligram per teaspoon equals 0.015 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 milligram per teaspoon?
Milligram per Teaspoon (mg/tsp) is a unit of density.
Is the carat per tablespoon to milligram per teaspoon conversion exact?
Yes. Both carat per tablespoon and milligram per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 66.66666667 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.
