About Converting Grams per Teaspoon to Carats per Cup
Gram per Teaspoon and Carat 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
carats per cup = grams per teaspoon × 240
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per teaspoon equals 202.884136211 base units, and 1 carat per cup equals 0.845350567546 base units, so dividing one by the other gives the direct gram per teaspoon-to-carat per cup factor of 240.
Simple example
1 g/tsp × 240 = 240 ct/cup
1 gram per teaspoon = 240 carats per cup.
Real-world example
1,000 g/tsp × 240 = 240,000 ct/cup
1,000 grams per teaspoon = 240,000 carats per cup.

Frequently asked questions
How many carats per cup are in 1 gram per teaspoon?
1 gram per teaspoon equals 240 carats per cup, using the exact defined conversion factor rather than an estimate.
How do I convert gram per teaspoon to carat per cup?
Multiply the gram per teaspoon value by 240. The converter above does this instantly to whatever precision you set.
How do I convert carat per cup back to gram per teaspoon?
Use the reverse factor: 1 carat per cup equals 0.0041666667 grams per teaspoon. You can also use the swap control in the converter above to flip the direction instantly.
What is a gram per teaspoon?
Gram per Teaspoon (g/tsp) is a unit of density.
What is a carat per cup?
Carat per Cup (ct/cup) is a unit of density.
Is the gram per teaspoon to carat per cup conversion exact?
Yes. Both gram per teaspoon and carat per cup are defined by fixed standards rather than physical artifacts, so the factor of 240 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.
