About Converting Carats per Cup to Decagrams per Teaspoon
Carat per Cup and Decagram 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
decagrams per teaspoon = carats per cup × 0.000416666666667
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 decagram per teaspoon equals 2028.84136211 base units, so dividing one by the other gives the direct carat per cup-to-decagram per teaspoon factor of 0.000416666666667.
Simple example
1 ct/cup × 0.0004166666667 = 0.0004166667 dag/tsp
1 carat per cup = 0.0004166667 decagrams per teaspoon.
Real-world example
1,000 ct/cup × 0.0004166666667 = 0.4166666667 dag/tsp
1,000 carats per cup = 0.4166666667 decagrams per teaspoon.

Frequently asked questions
How many decagrams per teaspoon are in 1 carat per cup?
1 carat per cup equals 0.0004166667 decagrams per teaspoon, using the exact defined conversion factor rather than an estimate.
How do I convert carat per cup to decagram per teaspoon?
Multiply the carat per cup value by 0.0004166666667. The converter above does this instantly to whatever precision you set.
How do I convert decagram per teaspoon back to carat per cup?
Use the reverse factor: 1 decagram per teaspoon equals 2,400 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 decagram per teaspoon?
Decagram per Teaspoon (dag/tsp) is a unit of density.
Is the carat per cup to decagram per teaspoon conversion exact?
Yes. Both carat per cup and decagram per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 0.0004166666667 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.
