About Converting Carats per Quart to Centigrams per Gallon
Carat per Quart and Centigram 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
centigrams per gallon = carats per quart × 80
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per quart equals 0.211337641887 base units, and 1 centigram per gallon equals 0.00264172052358 base units, so dividing one by the other gives the direct carat per quart-to-centigram per gallon factor of 80.
Simple example
1 ct/qt × 80 = 80 cg/gal
1 carat per quart = 80 centigrams per gallon.
Real-world example
1,000 ct/qt × 80 = 80,000 cg/gal
1,000 carats per quart = 80,000 centigrams per gallon.

Frequently asked questions
How many centigrams per gallon are in 1 carat per quart?
1 carat per quart equals 80 centigrams per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert carat per quart to centigram per gallon?
Multiply the carat per quart value by 80. The converter above does this instantly to whatever precision you set.
How do I convert centigram per gallon back to carat per quart?
Use the reverse factor: 1 centigram per gallon equals 0.0125 carats per quart. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per quart?
Carat per Quart (ct/qt) is a unit of density.
What is a centigram per gallon?
Centigram per Gallon (cg/gal) is a unit of density.
Is the carat per quart to centigram per gallon conversion exact?
Yes. Both carat per quart and centigram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 80 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.
