About Converting Grains per Teaspoon to Carats per Liter
Grain per Teaspoon and Carat per Liter 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 liter = grains per teaspoon × 65.7333544138
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per teaspoon equals 13.1466708828 base units, and 1 carat per liter equals 0.2 base units, so dividing one by the other gives the direct grain per teaspoon-to-carat per liter factor of 65.7333544138.
Simple example
1 gr/tsp × 65.73335441 = 65.73335441 ct/L
1 grain per teaspoon = 65.73335441 carats per liter.
Real-world example
1,000 gr/tsp × 65.73335441 = 65,733.35441 ct/L
1,000 grains per teaspoon = 65,733.35441 carats per liter.

Frequently asked questions
How many carats per liter are in 1 grain per teaspoon?
1 grain per teaspoon equals 65.73335441 carats per liter, using the exact defined conversion factor rather than an estimate.
How do I convert grain per teaspoon to carat per liter?
Multiply the grain per teaspoon value by 65.73335441. The converter above does this instantly to whatever precision you set.
How do I convert carat per liter back to grain per teaspoon?
Use the reverse factor: 1 carat per liter equals 0.0152129769 grains per teaspoon. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per teaspoon?
Grain per Teaspoon (gr/tsp) is a unit of density.
What is a carat per liter?
Carat per Liter (ct/L) is a unit of density.
Is the grain per teaspoon to carat per liter conversion exact?
Yes. Both grain per teaspoon and carat per liter are defined by fixed standards rather than physical artifacts, so the factor of 65.73335441 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.
