About Converting Carats per Quart to Grains per Teaspoon
Carat per Quart and Grain 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
grains per teaspoon = carats per quart × 0.0160753732843
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per quart equals 0.211337641887 base units, and 1 grain per teaspoon equals 13.1466708828 base units, so dividing one by the other gives the direct carat per quart-to-grain per teaspoon factor of 0.0160753732843.
Simple example
1 ct/qt × 0.01607537328 = 0.0160753733 gr/tsp
1 carat per quart = 0.0160753733 grains per teaspoon.
Real-world example
1,000 ct/qt × 0.01607537328 = 16.07537328 gr/tsp
1,000 carats per quart = 16.07537328 grains per teaspoon.

Multiply the carat per quart value by 0.01607537328. The converter above does this instantly to whatever precision you set.
How do I convert grain per teaspoon back to carat per quart?
Use the reverse factor: 1 grain per teaspoon equals 62.2069536 carats per quart. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per quart?
Carat per Quart (ct/qt) is a unit of density.
What is a grain per teaspoon?
Grain per Teaspoon (gr/tsp) is a unit of density.
Is the carat per quart to grain per teaspoon conversion exact?
Yes. Both carat per quart and grain per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 0.01607537328 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.
