About Converting Pounds per Gallon to Carats per Liter
Pound per Gallon and Carat per Liter 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 liter = pounds per gallon × 599.132136584
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 liter equals 0.2 base units, so dividing one by the other gives the direct pound per gallon-to-carat per liter factor of 599.132136584.
Simple example
1 lb/gal × 599.1321366 = 599.1321366 ct/L
1 pound per gallon = 599.1321366 carats per liter.
Real-world example
1,000 lb/gal × 599.1321366 = 599,132.1366 ct/L
1,000 pounds per gallon = 599,132.1366 carats per liter.

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.
