About Converting Carats per Tablespoon to Micrograms per Teaspoon
Carat per Tablespoon and Microgram 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
micrograms per teaspoon = carats per tablespoon × 66666.6666667
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 microgram per teaspoon equals 0.000202884136211 base units, so dividing one by the other gives the direct carat per tablespoon-to-microgram per teaspoon factor of 66666.6666667.
Simple example
1 ct/tbsp × 66666.66667 = 66,666.66667 ug/tsp
1 carat per tablespoon = 66,666.66667 micrograms per teaspoon.
Real-world example
1,000 ct/tbsp × 66666.66667 = 66,666,666.67 ug/tsp
1,000 carats per tablespoon = 66,666,666.67 micrograms per teaspoon.

Frequently asked questions
How many micrograms per teaspoon are in 1 carat per tablespoon?
1 carat per tablespoon equals 66,666.66667 micrograms per teaspoon, using the exact defined conversion factor rather than an estimate.
How do I convert carat per tablespoon to microgram per teaspoon?
Multiply the carat per tablespoon value by 66666.66667. The converter above does this instantly to whatever precision you set.
How do I convert microgram per teaspoon back to carat per tablespoon?
Use the reverse factor: 1 microgram per teaspoon equals 0.000015 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 microgram per teaspoon?
Microgram per Teaspoon (ug/tsp) is a unit of density.
Is the carat per tablespoon to microgram per teaspoon conversion exact?
Yes. Both carat per tablespoon and microgram per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 66666.66667 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.
