About Converting Carats per Cubic Millimeter to Grams per Quart
Carat per Cubic Millimeter and Gram per Quart 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
grams per quart = carats per cubic millimeter × 189270.5892
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 gram per quart equals 1.05668820943 base units, so dividing one by the other gives the direct carat per cubic millimeter-to-gram per quart factor of 189270.5892.
Simple example
1 ct/mm3 × 189270.5892 = 189,270.5892 g/qt
1 carat per cubic millimeter = 189,270.5892 grams per quart.
Real-world example
1,000 ct/mm3 × 189270.5892 = 189,270,589.2 g/qt
1,000 carats per cubic millimeter = 189,270,589.2 grams per quart.

Frequently asked questions
How many grams per quart are in 1 carat per cubic millimeter?
1 carat per cubic millimeter equals 189,270.5892 grams per quart, using the exact defined conversion factor rather than an estimate.
How do I convert carat per cubic millimeter to gram per quart?
Multiply the carat per cubic millimeter value by 189270.5892. The converter above does this instantly to whatever precision you set.
How do I convert gram per quart back to carat per cubic millimeter?
Use the reverse factor: 1 gram per quart equals 0.0000052834 carats per cubic millimeter. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per cubic millimeter?
Carat per Cubic Millimeter (ct/mm3) is a unit of density.
What is a gram per quart?
Gram per Quart (g/qt) is a unit of density.
Is the carat per cubic millimeter to gram per quart conversion exact?
Yes. Both carat per cubic millimeter and gram per quart are defined by fixed standards rather than physical artifacts, so the factor of 189270.5892 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.
