About Converting Pounds per Gallon to Decigrams per Cubic Centimeter
Pound per Gallon and Decigram 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
decigrams per cubic centimeter = pounds per gallon × 1.19826427317
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 decigram per cubic centimeter equals 100 base units, so dividing one by the other gives the direct pound per gallon-to-decigram per cubic centimeter factor of 1.19826427317.
Simple example
1 lb/gal × 1.198264273 = 1.198264273 dg/cm3
1 pound per gallon = 1.198264273 decigrams per cubic centimeter.
Real-world example
1,000 lb/gal × 1.198264273 = 1,198.264273 dg/cm3
1,000 pounds per gallon = 1,198.264273 decigrams 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.
Uses of the Pound per Gallon today
- US paint and coatings density specifications
- US fuel and petroleum liquid density specs
