About Converting Long tons per Quart to Carats per Gallon
Long ton 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 = long tons per quart × 20320938.176
This factor comes from each unit's defined relationship to the category's base unit: 1 long ton per quart equals 1073644.78876 base units, and 1 carat per gallon equals 0.0528344104716 base units, so dividing one by the other gives the direct long ton per quart-to-carat per gallon factor of 20320938.176.
Simple example
1 long ton/qt × 20320938.18 = 20,320,938.18 ct/gal
1 long ton per quart = 20,320,938.18 carats per gallon.
Real-world example
1,000 long ton/qt × 20320938.18 = 20,320,938,180 ct/gal
1,000 long tons per quart = 20,320,938,180 carats per gallon.

What is a long ton per quart?
Long ton per Quart (long ton/qt) is a unit of density.
What is a carat per gallon?
Carat per Gallon (ct/gal) is a unit of density.
Is the long ton per quart to carat per gallon conversion exact?
Yes. Both long ton per quart and carat per gallon are defined by fixed standards rather than physical artifacts, so the factor of 20320938.18 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.
