About Converting Carats per Milliliter to Grains per Liter
Carat per Milliliter and Grain per Liter 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
grains per liter = carats per milliliter × 3086.47167059
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 grain per liter equals 0.06479891 base units, so dividing one by the other gives the direct carat per milliliter-to-grain per liter factor of 3086.47167059.
Simple example
1 ct/mL × 3086.471671 = 3,086.471671 gr/L
1 carat per milliliter = 3,086.471671 grains per liter.
Real-world example
1,000 ct/mL × 3086.471671 = 3,086,471.671 gr/L
1,000 carats per milliliter = 3,086,471.671 grains per liter.

Frequently asked questions
How many grains per liter are in 1 carat per milliliter?
1 carat per milliliter equals 3,086.471671 grains per liter, using the exact defined conversion factor rather than an estimate.
How do I convert carat per milliliter to grain per liter?
Multiply the carat per milliliter value by 3086.471671. The converter above does this instantly to whatever precision you set.
How do I convert grain per liter back to carat per milliliter?
Use the reverse factor: 1 grain per liter equals 0.0003239946 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 grain per liter?
Grain per Liter (gr/L) is a unit of density.
Is the carat per milliliter to grain per liter conversion exact?
Yes. Both carat per milliliter and grain per liter are defined by fixed standards rather than physical artifacts, so the factor of 3086.471671 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.
