About Converting Pounds per Gallon to Stones per Cubic Centimeter
Pound per Gallon and Stone per Cubic Centimeter 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
stones per cubic centimeter = pounds per gallon × 0.0000188694323113
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 stone per cubic centimeter equals 6350293.18 base units, so dividing one by the other gives the direct pound per gallon-to-stone per cubic centimeter factor of 0.0000188694323113.
Simple example
1 lb/gal × 0.00001886943231 = 0.0000188694 st/cm3
1 pound per gallon = 0.0000188694 stones per cubic centimeter.
Real-world example
1,000 lb/gal × 0.00001886943231 = 0.0188694323 st/cm3
1,000 pounds per gallon = 0.0188694323 stones per cubic centimeter.

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.
