About These Units
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.
Pound per Cubic Inch (lb/in³)
Pounds per cubic inch (lb/in³) measures dense materials in engineering. Steel: 0.284 lb/in³. Aluminum: 0.098 lb/in³. Lead: 0.41 lb/in³. Used for metal stock, casting specifications, and precision manufacturing in US customary units.
