About Converting Ounce per Cubic inches to Carats per Teaspoon
Ounce 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 = ounce per cubic inches × 42.6350250122
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per cubic inch equals 1729.99404439 base units, and 1 carat per teaspoon equals 40.5768272422 base units, so dividing one by the other gives the direct ounce per cubic inch-to-carat per teaspoon factor of 42.6350250122.
Simple example
1 oz/in3 × 42.63502501 = 42.63502501 ct/tsp
1 ounce per cubic inch = 42.63502501 carats per teaspoon.
Real-world example
1,000 oz/in3 × 42.63502501 = 42,635.02501 ct/tsp
1,000 ounce per cubic inches = 42,635.02501 carats per teaspoon.
