About Converting Carats per Teaspoon to Milligram per Cubic inches
Carat per Teaspoon and Milligram per Cubic inch 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
milligram per cubic inches = carats per teaspoon × 664.935064935
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per teaspoon equals 40.5768272422 base units, and 1 milligram per cubic inch equals 0.0610237440947 base units, so dividing one by the other gives the direct carat per teaspoon-to-milligram per cubic inch factor of 664.935064935.
Simple example
1 ct/tsp × 664.9350649 = 664.9350649 mg/in3
1 carat per teaspoon = 664.9350649 milligram per cubic inches.
Real-world example
1,000 ct/tsp × 664.9350649 = 664,935.0649 mg/in3
1,000 carats per teaspoon = 664,935.0649 milligram per cubic inches.
