About Converting Grains per Tablespoon to Carats per Teaspoon
Grain 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 = grains per tablespoon × 0.107998183333
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per tablespoon equals 4.38222362759 base units, and 1 carat per teaspoon equals 40.5768272422 base units, so dividing one by the other gives the direct grain per tablespoon-to-carat per teaspoon factor of 0.107998183333.
Simple example
1 gr/tbsp × 0.1079981833 = 0.1079981833 ct/tsp
1 grain per tablespoon = 0.1079981833 carats per teaspoon.
Real-world example
1,000 gr/tbsp × 0.1079981833 = 107.9981833 ct/tsp
1,000 grains per tablespoon = 107.9981833 carats per teaspoon.

How do I convert carat per teaspoon back to grain per tablespoon?
Use the reverse factor: 1 carat per teaspoon equals 9.259415012 grains per tablespoon. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per tablespoon?
Grain per Tablespoon (gr/tbsp) is a unit of density.
What is a carat per teaspoon?
Carat per Teaspoon (ct/tsp) is a unit of density.
Is the grain per tablespoon to carat per teaspoon conversion exact?
Yes. Both grain per tablespoon and carat per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 0.1079981833 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.
