About Converting Carats per Quart to Kilograms per Milliliter
Carat per Quart and Kilogram per Milliliter 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
kilograms per milliliter = carats per quart × 2.113376e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per quart equals 0.211337641887 base units, and 1 kilogram per milliliter equals 1000000 base units, so dividing one by the other gives the direct carat per quart-to-kilogram per milliliter factor of 2.113376e-7.
Simple example
1 ct/qt × 2.113376e-7 = 2.113376e-7 kg/mL
1 carat per quart = 2.113376e-7 kilograms per milliliter.
Real-world example
1,000 ct/qt × 2.113376e-7 = 0.0002113376 kg/mL
1,000 carats per quart = 0.0002113376 kilograms per milliliter.

Frequently asked questions
How many kilograms per milliliter are in 1 carat per quart?
1 carat per quart equals 2.113376e-7 kilograms per milliliter, using the exact defined conversion factor rather than an estimate.
How do I convert carat per quart to kilogram per milliliter?
Multiply the carat per quart value by 2.113376e-7. The converter above does this instantly to whatever precision you set.
How do I convert kilogram per milliliter back to carat per quart?
Use the reverse factor: 1 kilogram per milliliter equals 4,731,764.73 carats per quart. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per quart?
Carat per Quart (ct/qt) is a unit of density.
What is a kilogram per milliliter?
Kilogram per Milliliter (kg/mL) is a unit of density.
Is the carat per quart to kilogram per milliliter conversion exact?
Yes. Both carat per quart and kilogram per milliliter are defined by fixed standards rather than physical artifacts, so the factor of 2.113376e-7 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.
