About Converting Grams per Tablespoon to Carats per Teaspoon
Gram per Tablespoon and Carat 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
carats per teaspoon = grams per tablespoon × 1.66666666667
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per tablespoon equals 67.6280454037 base units, and 1 carat per teaspoon equals 40.5768272422 base units, so dividing one by the other gives the direct gram per tablespoon-to-carat per teaspoon factor of 1.66666666667.
Simple example
1 g/tbsp × 1.666666667 = 1.666666667 ct/tsp
1 gram per tablespoon = 1.666666667 carats per teaspoon.
Real-world example
1,000 g/tbsp × 1.666666667 = 1,666.666667 ct/tsp
1,000 grams per tablespoon = 1,666.666667 carats per teaspoon.

Frequently asked questions
How many carats per teaspoon are in 1 gram per tablespoon?
1 gram per tablespoon equals 1.666666667 carats per teaspoon, using the exact defined conversion factor rather than an estimate.
How do I convert gram per tablespoon to carat per teaspoon?
Multiply the gram per tablespoon value by 1.666666667. The converter above does this instantly to whatever precision you set.
How do I convert carat per teaspoon back to gram per tablespoon?
Use the reverse factor: 1 carat per teaspoon equals 0.6 grams per tablespoon. You can also use the swap control in the converter above to flip the direction instantly.
What is a gram per tablespoon?
Gram per Tablespoon (g/tbsp) is a unit of density.
What is a carat per teaspoon?
Carat per Teaspoon (ct/tsp) is a unit of density.
Is the gram per tablespoon to carat per teaspoon conversion exact?
Yes. Both gram per tablespoon and carat per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 1.666666667 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.
