About Converting Pounds per Gallon to Carats per Tablespoon
Pound per Gallon and Carat per Tablespoon 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. Pound per Gallon is most often used for us paint and coatings density specifications.
Formula
carats per tablespoon = pounds per gallon × 8.85922597656
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per gallon equals 119.826427317 base units, and 1 carat per tablespoon equals 13.5256090807 base units, so dividing one by the other gives the direct pound per gallon-to-carat per tablespoon factor of 8.85922597656.
Simple example
1 lb/gal × 8.859225977 = 8.859225977 ct/tbsp
1 pound per gallon = 8.859225977 carats per tablespoon.
Real-world example
1,000 lb/gal × 8.859225977 = 8,859.225977 ct/tbsp
1,000 pounds per gallon = 8,859.225977 carats per tablespoon.

Understanding the Pound per Gallon
Pound per Gallon (lb/gal) measures density. The US customary unit for liquid density, based on the US gallon (231 cubic inches). It is classified as a US customary density unit.
Where it's used: United States (paint, fuel, and industrial liquid density specifications)
lb/gal vs. lb/ft³. Both are US customary density units; they're related through the real, fixed relationship between the US gallon and the cubic foot (1 cubic foot ≈ 7.48 US gallons), not a round conversion factor.
