About Converting Carats per Cup to Grams per Teaspoon
Carat per Cup and Gram 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
grams per teaspoon = carats per cup × 0.00416666666667
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 gram per teaspoon equals 202.884136211 base units, so dividing one by the other gives the direct carat per cup-to-gram per teaspoon factor of 0.00416666666667.
Simple example
1 ct/cup × 0.004166666667 = 0.0041666667 g/tsp
1 carat per cup = 0.0041666667 grams per teaspoon.
Real-world example
1,000 ct/cup × 0.004166666667 = 4.166666667 g/tsp
1,000 carats per cup = 4.166666667 grams per teaspoon.

How do I convert gram per teaspoon back to carat per cup?
Use the reverse factor: 1 gram per teaspoon equals 240 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 gram per teaspoon?
Gram per Teaspoon (g/tsp) is a unit of density.
Is the carat per cup to gram per teaspoon conversion exact?
Yes. Both carat per cup and gram per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 0.004166666667 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.
