About Converting Grains per Pint to Carats per Liter
Grain per Pint 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 pint × 0.684722441811
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per pint equals 0.136944488362 base units, and 1 carat per liter equals 0.2 base units, so dividing one by the other gives the direct grain per pint-to-carat per liter factor of 0.684722441811.
Simple example
1 gr/pt × 0.6847224418 = 0.6847224418 ct/L
1 grain per pint = 0.6847224418 carats per liter.
Real-world example
1,000 gr/pt × 0.6847224418 = 684.7224418 ct/L
1,000 grains per pint = 684.7224418 carats per liter.

Frequently asked questions
How many carats per liter are in 1 grain per pint?
1 grain per pint equals 0.6847224418 carats per liter, using the exact defined conversion factor rather than an estimate.
How do I convert grain per pint to carat per liter?
Multiply the grain per pint value by 0.6847224418. The converter above does this instantly to whatever precision you set.
How do I convert carat per liter back to grain per pint?
Use the reverse factor: 1 carat per liter equals 1.460445779 grains per pint. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per pint?
Grain per Pint (gr/pt) 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 pint to carat per liter conversion exact?
Yes. Both grain per pint and carat per liter are defined by fixed standards rather than physical artifacts, so the factor of 0.6847224418 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.
