About Converting Pounds per Gallon to Grams per Cubic Centimeter
Pound per Gallon and Gram 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 typically associated with united States (paint, fuel, and industrial liquid density specifications), while Gram per Cubic Centimeter is typically associated with standard density unit in chemistry and materials science worldwide.
Formula
grams per cubic centimeter = pounds per gallon × 0.119826427317
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 gram per cubic centimeter equals 1000 base units, so dividing one by the other gives the direct pound per gallon-to-gram per cubic centimeter factor of 0.119826427317.
Simple example
1 lb/gal × 0.1198264273 = 0.1198264273 g/cm3
1 pound per gallon = 0.1198264273 grams per cubic centimeter.
Real-world example
1,000 lb/gal × 0.1198264273 = 119.8264273 g/cm3
1,000 pounds per gallon = 119.8264273 grams per cubic centimeter.

Pound per Gallon vs. Gram per Cubic Centimeter
| Aspect | Pound per Gallon | Gram per Cubic Centimeter |
|---|---|---|
| Family | US customary density unit | metric derived density unit |
| Typical use | US paint and coatings density specifications | Material identification in chemistry and geology (mineral density tables) |
| Where it's used | United States (paint, fuel, and industrial liquid density specifications) | Standard density unit in chemistry and materials science worldwide |
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
- Industrial liquid handling and shipping weight calculations
Understanding the Gram per Cubic Centimeter
Gram per Cubic Centimeter (g/cm3) measures density. Numerically identical to kilograms per liter, since one cubic centimeter equals one milliliter — this is the form most commonly used in chemistry and materials-science textbooks. It is classified as a metric derived density unit.
Where it's used: Standard density unit in chemistry and materials science worldwide
Uses of the Gram per Cubic Centimeter today
- Material identification in chemistry and geology (mineral density tables)
- Materials science and engineering specifications
