About Converting Gram per Cubic inches to Carats per Teaspoon
Gram per Cubic inch 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 = gram per cubic inches × 1.50390625
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per cubic inch equals 61.0237440947 base units, and 1 carat per teaspoon equals 40.5768272422 base units, so dividing one by the other gives the direct gram per cubic inch-to-carat per teaspoon factor of 1.50390625.
Simple example
1 g/in3 × 1.50390625 = 1.50390625 ct/tsp
1 gram per cubic inch = 1.50390625 carats per teaspoon.
Real-world example
1,000 g/in3 × 1.50390625 = 1,503.90625 ct/tsp
1,000 gram per cubic inches = 1,503.90625 carats per teaspoon.

What is a gram per cubic inch?
Gram per Cubic inch (g/in3) 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 cubic inch to carat per teaspoon conversion exact?
Yes. Both gram per cubic inch and carat per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 1.50390625 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.
