About Converting Carats per Cubic Millimeter to Pounds per Teaspoon
Carat per Cubic Millimeter 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 = carats per cubic millimeter × 2.17328240938
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per cubic millimeter equals 200000 base units, and 1 pound per teaspoon equals 92026.6961794 base units, so dividing one by the other gives the direct carat per cubic millimeter-to-pound per teaspoon factor of 2.17328240938.
Simple example
1 ct/mm3 × 2.173282409 = 2.173282409 lb/tsp
1 carat per cubic millimeter = 2.173282409 pounds per teaspoon.
Real-world example
1,000 ct/mm3 × 2.173282409 = 2,173.282409 lb/tsp
1,000 carats per cubic millimeter = 2,173.282409 pounds per teaspoon.

What is a carat per cubic millimeter?
Carat per Cubic Millimeter (ct/mm3) is a unit of density.
What is a pound per teaspoon?
Pound per Teaspoon (lb/tsp) is a unit of density.
Is the carat per cubic millimeter to pound per teaspoon conversion exact?
Yes. Both carat per cubic millimeter and pound per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 2.173282409 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.
