About Converting Carats per Tablespoon to Grams per Cubic Millimeter
Carat per Tablespoon and Gram per Cubic Millimeter 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
grams per cubic millimeter = carats per tablespoon × 0.0000135256090807
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 gram per cubic millimeter equals 1000000 base units, so dividing one by the other gives the direct carat per tablespoon-to-gram per cubic millimeter factor of 0.0000135256090807.
Simple example
1 ct/tbsp × 0.00001352560908 = 0.0000135256 g/mm3
1 carat per tablespoon = 0.0000135256 grams per cubic millimeter.
Real-world example
1,000 ct/tbsp × 0.00001352560908 = 0.0135256091 g/mm3
1,000 carats per tablespoon = 0.0135256091 grams per cubic millimeter.

Frequently asked questions
How many grams per cubic millimeter are in 1 carat per tablespoon?
1 carat per tablespoon equals 0.0000135256 grams per cubic millimeter, using the exact defined conversion factor rather than an estimate.
How do I convert carat per tablespoon to gram per cubic millimeter?
Multiply the carat per tablespoon value by 0.00001352560908. The converter above does this instantly to whatever precision you set.
How do I convert gram per cubic millimeter back to carat per tablespoon?
Use the reverse factor: 1 gram per cubic millimeter equals 73,933.82391 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 gram per cubic millimeter?
Gram per Cubic Millimeter (g/mm3) is a unit of density.
Is the carat per tablespoon to gram per cubic millimeter conversion exact?
Yes. Both carat per tablespoon and gram per cubic millimeter are defined by fixed standards rather than physical artifacts, so the factor of 0.00001352560908 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.
