About Converting Grains per Teaspoon to Carats per Cubic Meter
Grain per Teaspoon and Carat per Cubic Meter 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 cubic meter = grains per teaspoon × 65733.3544138
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 cubic meter equals 0.0002 base units, so dividing one by the other gives the direct grain per teaspoon-to-carat per cubic meter factor of 65733.3544138.
Simple example
1 gr/tsp × 65733.35441 = 65,733.35441 ct/m3
1 grain per teaspoon = 65,733.35441 carats per cubic meter.
Real-world example
1,000 gr/tsp × 65733.35441 = 65,733,354.41 ct/m3
1,000 grains per teaspoon = 65,733,354.41 carats per cubic meter.

Frequently asked questions
How many carats per cubic meter are in 1 grain per teaspoon?
1 grain per teaspoon equals 65,733.35441 carats per cubic meter, using the exact defined conversion factor rather than an estimate.
How do I convert grain per teaspoon to carat per cubic meter?
Multiply the grain per teaspoon value by 65733.35441. The converter above does this instantly to whatever precision you set.
How do I convert carat per cubic meter back to grain per teaspoon?
Use the reverse factor: 1 carat per cubic meter equals 0.000015213 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 cubic meter?
Carat per Cubic Meter (ct/m3) is a unit of density.
Is the grain per teaspoon to carat per cubic meter conversion exact?
Yes. Both grain per teaspoon and carat per cubic meter are defined by fixed standards rather than physical artifacts, so the factor of 65733.35441 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.
