About Converting Grams per Quart to Carats per Gallon
Gram 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 = grams per quart × 20
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per quart equals 1.05668820943 base units, and 1 carat per gallon equals 0.0528344104716 base units, so dividing one by the other gives the direct gram per quart-to-carat per gallon factor of 20.
Simple example
1 g/qt × 20 = 20 ct/gal
1 gram per quart = 20 carats per gallon.
Real-world example
1,000 g/qt × 20 = 20,000 ct/gal
1,000 grams per quart = 20,000 carats per gallon.

Frequently asked questions
How many carats per gallon are in 1 gram per quart?
1 gram per quart equals 20 carats per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert gram per quart to carat per gallon?
Multiply the gram per quart value by 20. The converter above does this instantly to whatever precision you set.
How do I convert carat per gallon back to gram per quart?
Use the reverse factor: 1 carat per gallon equals 0.05 grams per quart. You can also use the swap control in the converter above to flip the direction instantly.
What is a gram per quart?
Gram per Quart (g/qt) is a unit of density.
What is a carat per gallon?
Carat per Gallon (ct/gal) is a unit of density.
Is the gram per quart to carat per gallon conversion exact?
Yes. Both gram per quart and carat per gallon are defined by fixed standards rather than physical artifacts, so the factor of 20 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.
