About Converting Carats per Cup to Drams per Liter
Carat per Cup and Dram 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
drams per liter = carats per cup × 0.477101820059
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 dram per liter equals 1.77184519531 base units, so dividing one by the other gives the direct carat per cup-to-dram per liter factor of 0.477101820059.
Simple example
1 ct/cup × 0.4771018201 = 0.4771018201 dr/L
1 carat per cup = 0.4771018201 drams per liter.
Real-world example
1,000 ct/cup × 0.4771018201 = 477.1018201 dr/L
1,000 carats per cup = 477.1018201 drams per liter.

What is a carat per cup?
Carat per Cup (ct/cup) is a unit of density.
What is a dram per liter?
Dram per Liter (dr/L) is a unit of density.
Is the carat per cup to dram per liter conversion exact?
Yes. Both carat per cup and dram per liter are defined by fixed standards rather than physical artifacts, so the factor of 0.4771018201 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.
