Density of some materials:
- Air ≈ 0.075 lb/ft³
- Aluminum = 168.6 lb/ft³
- Concrete ≈ 149.8 lb/ft³
- Diesel ≈ 53 lb/ft³,
- Gasoline (petrol) ≈ 44 lb/ft³
- Steel = 490 lb/ft³
- Water (4°C) = 62.4 lb/ft³
How to convert from ft3 to lb?
The mass (weight) in pounds is equal to the volume in cubic feet multiplied by the weight in pounds per cubic foot.
Formula:
m = V x p
m – mass (weight) in pounds (lb);
V – volume in cubic feet (ft3, cu ft, cf);
ρ – density in pounds per cubic foot (lb/ft3, lb/(cu ft), lb/cf, lb ft-3).
Example
Convert 4 ft3 to lb if the density is 12 lb/ft3.
Solution: m = V x p = 4 x 12 = 48 lb. Answer: 4 ft3 = 48 lb (density = 12 lb/ft3)
