About Converting Carat per Cubic inches to Pounds per Teaspoon
Carat per Cubic inch and Pound 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
pounds per teaspoon = carat per cubic inches × 0.000132621829596
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 pound per teaspoon equals 92026.6961794 base units, so dividing one by the other gives the direct carat per cubic inch-to-pound per teaspoon factor of 0.000132621829596.
