About Converting Carats per Tablespoon to Grams per Gallon
Carat per Tablespoon and Gram 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
grams per gallon = carats per tablespoon × 51.2
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 gallon equals 0.264172052358 base units, so dividing one by the other gives the direct carat per tablespoon-to-gram per gallon factor of 51.2.
Simple example
1 ct/tbsp × 51.2 = 51.2 g/gal
1 carat per tablespoon = 51.2 grams per gallon.
Real-world example
1,000 ct/tbsp × 51.2 = 51,200 g/gal
1,000 carats per tablespoon = 51,200 grams per gallon.

Frequently asked questions
How many grams per gallon are in 1 carat per tablespoon?
1 carat per tablespoon equals 51.2 grams per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert carat per tablespoon to gram per gallon?
Multiply the carat per tablespoon value by 51.2. The converter above does this instantly to whatever precision you set.
How do I convert gram per gallon back to carat per tablespoon?
Use the reverse factor: 1 gram per gallon equals 0.01953125 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 gallon?
Gram per Gallon (g/gal) is a unit of density.
Is the carat per tablespoon to gram per gallon conversion exact?
Yes. Both carat per tablespoon and gram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 51.2 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.
