About Converting Carats per Teaspoon to Ounces per Cubic Millimeter
Carat per Teaspoon and Ounce per Cubic Millimeter 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
ounces per cubic millimeter = carats per teaspoon × 0.00000143130546018
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 ounce per cubic millimeter equals 28349523.125 base units, so dividing one by the other gives the direct carat per teaspoon-to-ounce per cubic millimeter factor of 0.00000143130546018.
Simple example
1 ct/tsp × 0.00000143130546 = 0.0000014313 oz/mm3
1 carat per teaspoon = 0.0000014313 ounces per cubic millimeter.
Real-world example
1,000 ct/tsp × 0.00000143130546 = 0.0014313055 oz/mm3
1,000 carats per teaspoon = 0.0014313055 ounces per cubic millimeter.

Frequently asked questions
How many ounces per cubic millimeter are in 1 carat per teaspoon?
1 carat per teaspoon equals 0.0000014313 ounces per cubic millimeter, using the exact defined conversion factor rather than an estimate.
How do I convert carat per teaspoon to ounce per cubic millimeter?
Multiply the carat per teaspoon value by 0.00000143130546. The converter above does this instantly to whatever precision you set.
How do I convert ounce per cubic millimeter back to carat per teaspoon?
Use the reverse factor: 1 ounce per cubic millimeter equals 698,662.8835 carats per teaspoon. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per teaspoon?
Carat per Teaspoon (ct/tsp) is a unit of density.
What is a ounce per cubic millimeter?
Ounce per Cubic Millimeter (oz/mm3) is a unit of density.
Is the carat per teaspoon to ounce per cubic millimeter conversion exact?
Yes. Both carat per teaspoon and ounce per cubic millimeter are defined by fixed standards rather than physical artifacts, so the factor of 0.00000143130546 used above is exact to as many digits as you choose to display.
What's the difference between density and mass concentration?
Density is the mass of a pure substance or material per unit volume. Mass concentration is the mass of one component — like a dissolved solute — within a mixture's total volume. The two use the same kind of units but describe different physical situations.
