About Converting Carat per Cubic inches to Grains per Teaspoon
Carat per Cubic inch and Grain 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
grains per teaspoon = carat per cubic inches × 0.928352807169
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per cubic inch equals 12.2047488189 base units, and 1 grain per teaspoon equals 13.1466708828 base units, so dividing one by the other gives the direct carat per cubic inch-to-grain per teaspoon factor of 0.928352807169.
Simple example
1 ct/in3 × 0.9283528072 = 0.9283528072 gr/tsp
1 carat per cubic inch = 0.9283528072 grains per teaspoon.
Real-world example
1,000 ct/in3 × 0.9283528072 = 928.3528072 gr/tsp
1,000 carat per cubic inches = 928.3528072 grains per teaspoon.

Frequently asked questions
How many grains per teaspoon are in 1 carat per cubic inch?
1 carat per cubic inch equals 0.9283528072 grains per teaspoon, using the exact defined conversion factor rather than an estimate.
How do I convert carat per cubic inch to grain per teaspoon?
Multiply the carat per cubic inch value by 0.9283528072. The converter above does this instantly to whatever precision you set.
How do I convert grain per teaspoon back to carat per cubic inch?
Use the reverse factor: 1 grain per teaspoon equals 1.077176686 carat per cubic inches. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per cubic inch?
Carat per Cubic inch (ct/in3) is a unit of density.
What is a grain per teaspoon?
Grain per Teaspoon (gr/tsp) is a unit of density.
Is the carat per cubic inch to grain per teaspoon conversion exact?
Yes. Both carat per cubic inch and grain per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 0.9283528072 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.
