About Converting Carats per Teaspoon to Grams per Teaspoon
Carat per Teaspoon 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 teaspoon × 0.2
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per teaspoon equals 40.5768272422 base units, and 1 gram per teaspoon equals 202.884136211 base units, so dividing one by the other gives the direct carat per teaspoon-to-gram per teaspoon factor of 0.2.
Simple example
1 ct/tsp × 0.2 = 0.2 g/tsp
1 carat per teaspoon = 0.2 grams per teaspoon.
Real-world example
1,000 ct/tsp × 0.2 = 200 g/tsp
1,000 carats per teaspoon = 200 grams per teaspoon.

Frequently asked questions
How many grams per teaspoon are in 1 carat per teaspoon?
1 carat per teaspoon equals 0.2 grams per teaspoon, using the exact defined conversion factor rather than an estimate.
How do I convert carat per teaspoon to gram per teaspoon?
Multiply the carat per teaspoon value by 0.2. The converter above does this instantly to whatever precision you set.
How do I convert gram per teaspoon back to carat per teaspoon?
Use the reverse factor: 1 gram per teaspoon equals 5 carats per teaspoon. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per teaspoon?
Carat per Teaspoon (ct/tsp) 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 teaspoon to gram per teaspoon conversion exact?
Yes. Both carat per teaspoon and gram per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 0.2 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.
