About Converting Dram per Cubic inches to Carats per Teaspoon
Dram 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 = dram per cubic inches × 2.66468906326
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per cubic inch equals 108.124627774 base units, and 1 carat per teaspoon equals 40.5768272422 base units, so dividing one by the other gives the direct dram per cubic inch-to-carat per teaspoon factor of 2.66468906326.
Simple example
1 dr/in3 × 2.664689063 = 2.664689063 ct/tsp
1 dram per cubic inch = 2.664689063 carats per teaspoon.
Real-world example
1,000 dr/in3 × 2.664689063 = 2,664.689063 ct/tsp
1,000 dram per cubic inches = 2,664.689063 carats per teaspoon.
