About Converting Carats per Cup to Carats per Liter
Carat per Cup 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 = carats per cup × 4.22675283773
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per cup equals 0.845350567546 base units, and 1 carat per liter equals 0.2 base units, so dividing one by the other gives the direct carat per cup-to-carat per liter factor of 4.22675283773.
Simple example
1 ct/cup × 4.226752838 = 4.226752838 ct/L
1 carat per cup = 4.226752838 carats per liter.
Real-world example
1,000 ct/cup × 4.226752838 = 4,226.752838 ct/L
1,000 carats per cup = 4,226.752838 carats per liter.

What is a carat per cup?
Carat per Cup (ct/cup) is a unit of density.
What is a carat per liter?
Carat per Liter (ct/L) is a unit of density.
Is the carat per cup to carat per liter conversion exact?
Yes. Both carat per cup and carat per liter are defined by fixed standards rather than physical artifacts, so the factor of 4.226752838 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.
