About Converting Carats per Tablespoon to Carats per Gallon
Carat per Tablespoon and Carat per Gallon 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 gallon = carats per tablespoon × 256
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 carat per gallon equals 0.0528344104716 base units, so dividing one by the other gives the direct carat per tablespoon-to-carat per gallon factor of 256.
Simple example
1 ct/tbsp × 256 = 256 ct/gal
1 carat per tablespoon = 256 carats per gallon.
Real-world example
1,000 ct/tbsp × 256 = 256,000 ct/gal
1,000 carats per tablespoon = 256,000 carats per gallon.

Frequently asked questions
How many carats per gallon are in 1 carat per tablespoon?
1 carat per tablespoon equals 256 carats per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert carat per tablespoon to carat per gallon?
Multiply the carat per tablespoon value by 256. The converter above does this instantly to whatever precision you set.
How do I convert carat per gallon back to carat per tablespoon?
Use the reverse factor: 1 carat per gallon equals 0.00390625 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 carat per gallon?
Carat per Gallon (ct/gal) is a unit of density.
Is the carat per tablespoon to carat per gallon conversion exact?
Yes. Both carat per tablespoon and carat per gallon are defined by fixed standards rather than physical artifacts, so the factor of 256 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.
