About Converting Grains per Milliliter to Carats per Liter
Grain per Milliliter and Carat 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
carats per liter = grains per milliliter × 323.99455
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per milliliter equals 64.79891 base units, and 1 carat per liter equals 0.2 base units, so dividing one by the other gives the direct grain per milliliter-to-carat per liter factor of 323.99455.
Simple example
1 gr/mL × 323.99455 = 323.99455 ct/L
1 grain per milliliter = 323.99455 carats per liter.
Real-world example
1,000 gr/mL × 323.99455 = 323,994.55 ct/L
1,000 grains per milliliter = 323,994.55 carats per liter.

Frequently asked questions
How many carats per liter are in 1 grain per milliliter?
1 grain per milliliter equals 323.99455 carats per liter, using the exact defined conversion factor rather than an estimate.
How do I convert grain per milliliter to carat per liter?
Multiply the grain per milliliter value by 323.99455. The converter above does this instantly to whatever precision you set.
How do I convert carat per liter back to grain per milliliter?
Use the reverse factor: 1 carat per liter equals 0.0030864717 grains per milliliter. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per milliliter?
Grain per Milliliter (gr/mL) is a unit of density.
What is a carat per liter?
Carat per Liter (ct/L) is a unit of density.
Is the grain per milliliter to carat per liter conversion exact?
Yes. Both grain per milliliter and carat per liter are defined by fixed standards rather than physical artifacts, so the factor of 323.99455 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.
