About Converting Carats per Liter to Drams per Cubic Millimeter
Carat per Liter and Dram 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
drams per cubic millimeter = carats per liter × 1.128767e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per liter equals 0.2 base units, and 1 dram per cubic millimeter equals 1771845.19531 base units, so dividing one by the other gives the direct carat per liter-to-dram per cubic millimeter factor of 1.128767e-7.
Simple example
1 ct/L × 1.128767e-7 = 1.128767e-7 dr/mm3
1 carat per liter = 1.128767e-7 drams per cubic millimeter.
Real-world example
1,000 ct/L × 1.128767e-7 = 0.0001128767 dr/mm3
1,000 carats per liter = 0.0001128767 drams per cubic millimeter.

Frequently asked questions
How many drams per cubic millimeter are in 1 carat per liter?
1 carat per liter equals 1.128767e-7 drams per cubic millimeter, using the exact defined conversion factor rather than an estimate.
How do I convert carat per liter to dram per cubic millimeter?
Multiply the carat per liter value by 1.128767e-7. The converter above does this instantly to whatever precision you set.
How do I convert dram per cubic millimeter back to carat per liter?
Use the reverse factor: 1 dram per cubic millimeter equals 8,859,225.977 carats per liter. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per liter?
Carat per Liter (ct/L) is a unit of density.
What is a dram per cubic millimeter?
Dram per Cubic Millimeter (dr/mm3) is a unit of density.
Is the carat per liter to dram per cubic millimeter conversion exact?
Yes. Both carat per liter and dram per cubic millimeter are defined by fixed standards rather than physical artifacts, so the factor of 1.128767e-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.
