About Converting Carats per Tablespoon to Grains per Gallon
Carat per Tablespoon and Grain 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
grains per gallon = carats per tablespoon × 790.136747671
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 gallon equals 0.0171180610453 base units, so dividing one by the other gives the direct carat per tablespoon-to-grain per gallon factor of 790.136747671.
Simple example
1 ct/tbsp × 790.1367477 = 790.1367477 gr/gal
1 carat per tablespoon = 790.1367477 grains per gallon.
Real-world example
1,000 ct/tbsp × 790.1367477 = 790,136.7477 gr/gal
1,000 carats per tablespoon = 790,136.7477 grains per gallon.

What is a carat per tablespoon?
Carat per Tablespoon (ct/tbsp) is a unit of density.
What is a grain per gallon?
Grain per Gallon (gr/gal) is a unit of density.
Is the carat per tablespoon to grain per gallon conversion exact?
