About Converting Carats per Liter to Grains per Cubic foot
Carat per Liter and Grain per Cubic foot 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 cubic foot = carats per liter × 87.3991448066
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 grain per cubic foot equals 0.00228835191057 base units, so dividing one by the other gives the direct carat per liter-to-grain per cubic foot factor of 87.3991448066.
Simple example
1 ct/L × 87.39914481 = 87.39914481 gr/ft3
1 carat per liter = 87.39914481 grains per cubic foot.
Real-world example
1,000 ct/L × 87.39914481 = 87,399.14481 gr/ft3
1,000 carats per liter = 87,399.14481 grains per cubic foot.

What is a carat per liter?
Carat per Liter (ct/L) is a unit of density.
What is a grain per cubic foot?
Grain per Cubic foot (gr/ft3) is a unit of density.
Is the carat per liter to grain per cubic foot conversion exact?
Yes. Both carat per liter and grain per cubic foot are defined by fixed standards rather than physical artifacts, so the factor of 87.39914481 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.
