About Converting Carats per Cup to Centigrams per Gallon
Carat per Cup 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 cup × 320
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per cup equals 0.845350567546 base units, and 1 centigram per gallon equals 0.00264172052358 base units, so dividing one by the other gives the direct carat per cup-to-centigram per gallon factor of 320.
Simple example
1 ct/cup × 320 = 320 cg/gal
1 carat per cup = 320 centigrams per gallon.
Real-world example
1,000 ct/cup × 320 = 320,000 cg/gal
1,000 carats per cup = 320,000 centigrams per gallon.

Frequently asked questions
How many centigrams per gallon are in 1 carat per cup?
1 carat per cup equals 320 centigrams per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert carat per cup to centigram per gallon?
Multiply the carat per cup value by 320. The converter above does this instantly to whatever precision you set.
How do I convert centigram per gallon back to carat per cup?
Use the reverse factor: 1 centigram per gallon equals 0.003125 carats per cup. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per cup?
Carat per Cup (ct/cup) 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 cup to centigram per gallon conversion exact?
Yes. Both carat per cup and centigram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 320 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.
