About Converting Carats per Cubic Meter to Metric tons per Cubic Millimeter
Carat per Cubic Meter and Metric ton 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
metric tons per cubic millimeter = carats per cubic meter × 2e-16
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per cubic meter equals 0.0002 base units, and 1 metric ton per cubic millimeter equals 1000000000000 base units, so dividing one by the other gives the direct carat per cubic meter-to-metric ton per cubic millimeter factor of 2e-16.
Simple example
1 ct/m3 × 2e-16 = 2e-16 t/mm3
1 carat per cubic meter = 2e-16 metric tons per cubic millimeter.
Real-world example
1,000 ct/m3 × 2e-16 = 2e-13 t/mm3
1,000 carats per cubic meter = 2e-13 metric tons per cubic millimeter.

Frequently asked questions
How many metric tons per cubic millimeter are in 1 carat per cubic meter?
1 carat per cubic meter equals 2e-16 metric tons per cubic millimeter, using the exact defined conversion factor rather than an estimate.
How do I convert carat per cubic meter to metric ton per cubic millimeter?
Multiply the carat per cubic meter value by 2e-16. The converter above does this instantly to whatever precision you set.
How do I convert metric ton per cubic millimeter back to carat per cubic meter?
Use the reverse factor: 1 metric ton per cubic millimeter equals 5e+15 carats per cubic meter. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per cubic meter?
Carat per Cubic Meter (ct/m3) is a unit of density.
What is a metric ton per cubic millimeter?
Metric ton per Cubic Millimeter (t/mm3) is a unit of density.
Is the carat per cubic meter to metric ton per cubic millimeter conversion exact?
Yes. Both carat per cubic meter and metric ton per cubic millimeter are defined by fixed standards rather than physical artifacts, so the factor of 2e-16 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.
