About Converting Pounds per Quart to Carats per Gallon
Pound per Quart and Carat per Gallon 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 gallon = pounds per quart × 9071.8474
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per quart equals 479.305709268 base units, and 1 carat per gallon equals 0.0528344104716 base units, so dividing one by the other gives the direct pound per quart-to-carat per gallon factor of 9071.8474.
Simple example
1 lb/qt × 9071.8474 = 9,071.8474 ct/gal
1 pound per quart = 9,071.8474 carats per gallon.
Real-world example
1,000 lb/qt × 9071.8474 = 9,071,847.4 ct/gal
1,000 pounds per quart = 9,071,847.4 carats per gallon.

What is a pound per quart?
Pound per Quart (lb/qt) is a unit of density.
What is a carat per gallon?
Carat per Gallon (ct/gal) is a unit of density.
Is the pound per quart to carat per gallon conversion exact?
Yes. Both pound per quart and carat per gallon are defined by fixed standards rather than physical artifacts, so the factor of 9071.8474 used above is exact to as many digits as you choose to display.
