About Converting Metric tons per Cubic Millimeter to Carats per Cup
Metric ton per Cubic Millimeter and Carat per Cup 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 cup = metric tons per cubic millimeter × 1.182941e+12
This factor comes from each unit's defined relationship to the category's base unit: 1 metric ton per cubic millimeter equals 1000000000000 base units, and 1 carat per cup equals 0.845350567546 base units, so dividing one by the other gives the direct metric ton per cubic millimeter-to-carat per cup factor of 1.182941e+12.
Simple example
1 t/mm3 × 1.182941e+12 = 1.182941e+12 ct/cup
1 metric ton per cubic millimeter = 1.182941e+12 carats per cup.
Real-world example
1,000 t/mm3 × 1.182941e+12 = 1.182941e+15 ct/cup
1,000 metric tons per cubic millimeter = 1.182941e+15 carats per cup.

Frequently asked questions
How many carats per cup are in 1 metric ton per cubic millimeter?
1 metric ton per cubic millimeter equals 1.182941e+12 carats per cup, using the exact defined conversion factor rather than an estimate.
How do I convert metric ton per cubic millimeter to carat per cup?
Multiply the metric ton per cubic millimeter value by 1.182941e+12. The converter above does this instantly to whatever precision you set.
How do I convert carat per cup back to metric ton per cubic millimeter?
Use the reverse factor: 1 carat per cup equals 8.453506e-13 metric tons per cubic millimeter. You can also use the swap control in the converter above to flip the direction instantly.
What is a metric ton per cubic millimeter?
Metric ton per Cubic Millimeter (t/mm3) is a unit of density.
What is a carat per cup?
Carat per Cup (ct/cup) is a unit of density.
Is the metric ton per cubic millimeter to carat per cup conversion exact?
Yes. Both metric ton per cubic millimeter and carat per cup are defined by fixed standards rather than physical artifacts, so the factor of 1.182941e+12 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.
