About Converting Carats per Cup to Centigrams per Teaspoon
Carat per Cup and Centigram per Teaspoon 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 teaspoon = carats per cup × 0.416666666667
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 teaspoon equals 2.02884136211 base units, so dividing one by the other gives the direct carat per cup-to-centigram per teaspoon factor of 0.416666666667.
Simple example
1 ct/cup × 0.4166666667 = 0.4166666667 cg/tsp
1 carat per cup = 0.4166666667 centigrams per teaspoon.
Real-world example
1,000 ct/cup × 0.4166666667 = 416.6666667 cg/tsp
1,000 carats per cup = 416.6666667 centigrams per teaspoon.

Frequently asked questions
How many centigrams per teaspoon are in 1 carat per cup?
1 carat per cup equals 0.4166666667 centigrams per teaspoon, using the exact defined conversion factor rather than an estimate.

Multiply the carat per cup value by 0.4166666667. The converter above does this instantly to whatever precision you set.
How do I convert centigram per teaspoon back to carat per cup?
Use the reverse factor: 1 centigram per teaspoon equals 2.4 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 teaspoon?
Centigram per Teaspoon (cg/tsp) is a unit of density.
Is the carat per cup to centigram per teaspoon conversion exact?
Yes. Both carat per cup and centigram per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 0.4166666667 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.
