About Converting Carats per Milliliter to Carats per Cup
Carat per Milliliter 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 = carats per milliliter × 236.5882365
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per milliliter equals 200 base units, and 1 carat per cup equals 0.845350567546 base units, so dividing one by the other gives the direct carat per milliliter-to-carat per cup factor of 236.5882365.
Simple example
1 ct/mL × 236.5882365 = 236.5882365 ct/cup
1 carat per milliliter = 236.5882365 carats per cup.
Real-world example
1,000 ct/mL × 236.5882365 = 236,588.2365 ct/cup
1,000 carats per milliliter = 236,588.2365 carats per cup.

Frequently asked questions
How many carats per cup are in 1 carat per milliliter?
1 carat per milliliter equals 236.5882365 carats per cup, using the exact defined conversion factor rather than an estimate.
How do I convert carat per milliliter to carat per cup?
Multiply the carat per milliliter value by 236.5882365. The converter above does this instantly to whatever precision you set.
How do I convert carat per cup back to carat per milliliter?
Use the reverse factor: 1 carat per cup equals 0.0042267528 carats per milliliter. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per milliliter?
Carat per Milliliter (ct/mL) is a unit of density.
What is a carat per cup?
Carat per Cup (ct/cup) is a unit of density.
Is the carat per milliliter to carat per cup conversion exact?
Yes. Both carat per milliliter and carat per cup are defined by fixed standards rather than physical artifacts, so the factor of 236.5882365 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.
