About These Units
Pound per Cubic Foot (lb/ft³)
Pounds per cubic foot (lb/ft³ or PCF) is the standard imperial density unit. Water: 62.4 lb/ft³. Concrete: 150 lb/ft³. Oak wood: 45 lb/ft³. Air: 0.075 lb/ft³. Used in US construction, material specifications, and structural engineering.
Specific Gravity (SG)
Specific gravity (SG) is the dimensionless ratio of a substance's density to water at 4°C. Water = 1.0 by definition. Gasoline: 0.72-0.78. Honey: 1.4. Mercury: 13.6. Gold: 19.3. Also called relative density. Objects with SG < 1 float in water.
