How to Convert Pound per Cubic Foot to Kilogram per Cubic Meter
- 1 lb/ft³ = 16.01846337 kg/m³
- 1 kg/m³ = 0.06242796058 lb/ft³
- Example: convert 15 lb/ft³ to kg/m³: 15 lb/ft³ = 15 × 16.01846337 kg/m³ = 240.2769506 kg/m³
Formula
kg/m³ = lb/ft³ × 16.01846337396
Derivation from SI units:
- 1 lb/ft³ = 0.45359237 kg ÷ 0.028316846592 m³ = 16.018463374 kg/m³
- 1 kg/m³ = 1 kg ÷ 1 m³
Both units are defined exactly, so the factor is exact. Pound per Cubic Foot definition: pound per cubic foot; Kilogram per Cubic Meter definition: kilogram per cubic meter.
Worked examples
- Concrete at 145 lb/ft³ is 2322.677189 kg/m³.
145 lb/ft³ × 16.01846337 = 2322.677189 kg/m³ - Standard air at 0.075 lb/ft³ is 1.201384753 kg/m³.
0.075 lb/ft³ × 16.01846337 = 1.201384753 kg/m³
