About Converting Carats per Tablespoon to Grains per Cubic yard
Carat per Tablespoon and Grain per Cubic yard 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 cubic yard = carats per tablespoon × 159587.099997
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per tablespoon equals 13.5256090807 base units, and 1 grain per cubic yard equals 0.0000847537744654 base units, so dividing one by the other gives the direct carat per tablespoon-to-grain per cubic yard factor of 159587.099997.
Simple example
1 ct/tbsp × 159587.1 = 159,587.1 gr/yd3
1 carat per tablespoon = 159,587.1 grains per cubic yard.
Real-world example
1,000 ct/tbsp × 159587.1 = 159,587,100 gr/yd3
1,000 carats per tablespoon = 159,587,100 grains per cubic yard.

How do I convert grain per cubic yard back to carat per tablespoon?
Use the reverse factor: 1 grain per cubic yard equals 0.0000062662 carats per tablespoon. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per tablespoon?
Carat per Tablespoon (ct/tbsp) is a unit of density.
What is a grain per cubic yard?
Grain per Cubic yard (gr/yd3) is a unit of density.
Is the carat per tablespoon to grain per cubic yard conversion exact?
Yes. Both carat per tablespoon and grain per cubic yard are defined by fixed standards rather than physical artifacts, so the factor of 159587.1 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.
