About Converting Carats per Liter to Pounds per Quart
Carat per Liter and Pound per Quart 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
pounds per quart = carats per liter × 0.000417270222601
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 pound per quart equals 479.305709268 base units, so dividing one by the other gives the direct carat per liter-to-pound per quart factor of 0.000417270222601.
Simple example
1 ct/L × 0.0004172702226 = 0.0004172702 lb/qt
1 carat per liter = 0.0004172702 pounds per quart.
Real-world example
1,000 ct/L × 0.0004172702226 = 0.4172702226 lb/qt
1,000 carats per liter = 0.4172702226 pounds per quart.

What is a carat per liter?
Carat per Liter (ct/L) is a unit of density.
What is a pound per quart?
Pound per Quart (lb/qt) is a unit of density.
Is the carat per liter to pound per quart conversion exact?
