How to Convert Kilogram per Cubic Meter to Pound per Cubic Foot
- 1 kg/m³ = 0.06242796058 lb/ft³
- 1 lb/ft³ = 16.01846337 kg/m³
- Example: convert 15 kg/m³ to lb/ft³: 15 kg/m³ = 15 × 0.06242796058 lb/ft³ = 0.9364194086 lb/ft³
Formula
lb/ft³ = kg/m³ × 0.06242796057614
or lb/ft³ = kg/m³ ÷ 16.01846337396
Derivation from SI units:
- 1 kg/m³ = 1 kg ÷ 1 m³
- 1 lb/ft³ = 0.45359237 kg ÷ 0.028316846592 m³ = 16.018463374 kg/m³
Both units are defined exactly, so the factor is exact. Kilogram per Cubic Meter definition: kilogram per cubic meter; Pound per Cubic Foot definition: pound per cubic foot.
Worked examples
- Air at about 1.2 kg/m³ is 0.07491355269 lb/ft³.
1.2 kg/m³ × 0.06242796058 = 0.07491355269 lb/ft³ - Normal concrete at about 2400 kg/m³ is 149.8271054 lb/ft³.
2400 kg/m³ × 0.06242796058 = 149.8271054 lb/ft³
