How to Convert Pound-force per Cubic Foot to Kilogram-force per Cubic Metre
- 1 lbf/ft³ = 16.01846337 kgf/m³
- 1 kgf/m³ = 0.06242796058 lbf/ft³
- Example: convert 15 lbf/ft³ to kgf/m³: 15 lbf/ft³ = 15 × 16.01846337 kgf/m³ = 240.2769506 kgf/m³
Formula
kgf/m³ = lbf/ft³ × 16.01846337396
Derivation from SI units:
- 1 lbf/ft³ = 4.4482216152605 N ÷ 0.028316846592 m³ ≈ 157.087 N/m³.
- 1 kgf/m³ = 9.80665 N/m³.
- 1 lbf/ft³ = 157.0874638462 N/m³ ÷ 9.80665 N/m³ per kgf/m³ = 16.01846337396 kgf/m³
Both units are defined exactly, so the factor is exact. Pound-force per Cubic Foot definition: pound-force per cubic foot; Kilogram-force per Cubic Metre definition: kilogram-force per cubic metre.
Worked examples
- A reading of 110 lbf/ft³ converts to 1762.030971 kgf/m³.
110 lbf/ft³ × 16.01846337 = 1762.030971 kgf/m³ - A value of 125 lbf/ft³ is 2002.307922 kgf/m³.
125 lbf/ft³ × 16.01846337 = 2002.307922 kgf/m³
