About Converting Carats per Teaspoon to Pound per Cubic inches
Carat per Teaspoon and Pound 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
pound per cubic inches = carats per teaspoon × 0.00146593088622
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 pound per cubic inch equals 27679.9047102 base units, so dividing one by the other gives the direct carat per teaspoon-to-pound per cubic inch factor of 0.00146593088622.
Simple example
1 ct/tsp × 0.001465930886 = 0.0014659309 lb/in3
1 carat per teaspoon = 0.0014659309 pound per cubic inches.
Real-world example
1,000 ct/tsp × 0.001465930886 = 1.465930886 lb/in3
1,000 carats per teaspoon = 1.465930886 pound per cubic inches.
