About Converting Carats per Teaspoon to Dram per Cubic inches
Carat per Teaspoon and Dram 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
dram per cubic inches = carats per teaspoon × 0.375278306871
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 dram per cubic inch equals 108.124627774 base units, so dividing one by the other gives the direct carat per teaspoon-to-dram per cubic inch factor of 0.375278306871.
Simple example
1 ct/tsp × 0.3752783069 = 0.3752783069 dr/in3
1 carat per teaspoon = 0.3752783069 dram per cubic inches.
Real-world example
1,000 ct/tsp × 0.3752783069 = 375.2783069 dr/in3
1,000 carats per teaspoon = 375.2783069 dram per cubic inches.
