About Density Units
Gram per Cubic Centimeter (g/cm³)
A metric unit of density representing the mass in grams of one cubic centimeter of a substance. It’s widely used in scientific contexts and is numerically equal to kg/L and g/mL.
Pound per Cubic Foot (lb/ft³)
An imperial unit of density representing the mass in pounds of one cubic foot of a substance. Commonly used in engineering and construction in the United States.
Mathematical Relationship:
The conversion derives from:
- 1 pound (lb) = 453.592 grams (g)
- 1 foot (ft) = 30.48 centimeters (cm)
- 1 cubic foot (ft³) = 28,316.847 cubic centimeters (cm³)
Therefore: 1 g/cm³ = (1 g) / (1 cm³) × (1 lb / 453.592 g) × (28,316.847 cm³ / 1 ft³) = 62.428 lb/ft³
