About Converting Carats per Cup to Centigrams per Cup
Carat per Cup and Centigram per Cup 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 cup = carats per cup × 20
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 cup equals 0.0422675283773 base units, so dividing one by the other gives the direct carat per cup-to-centigram per cup factor of 20.
Simple example
1 ct/cup × 20 = 20 cg/cup
1 carat per cup = 20 centigrams per cup.
Real-world example
1,000 ct/cup × 20 = 20,000 cg/cup
1,000 carats per cup = 20,000 centigrams per cup.

Frequently asked questions
How many centigrams per cup are in 1 carat per cup?
1 carat per cup equals 20 centigrams per cup, using the exact defined conversion factor rather than an estimate.
How do I convert carat per cup to centigram per cup?
Multiply the carat per cup value by 20. The converter above does this instantly to whatever precision you set.
How do I convert centigram per cup back to carat per cup?
Use the reverse factor: 1 centigram per cup equals 0.05 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 cup?
Centigram per Cup (cg/cup) is a unit of density.
Is the carat per cup to centigram per cup conversion exact?
Yes. Both carat per cup and centigram per cup 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.
