How to Convert Gram-force per Cubic Centimetre to Pound-force per Cubic Foot
- 1 gf/cm³ = 62.42796058 lbf/ft³
- 1 lbf/ft³ = 0.01601846337 gf/cm³
- Example: convert 15 gf/cm³ to lbf/ft³: 15 gf/cm³ = 15 × 62.42796058 lbf/ft³ = 936.4194086 lbf/ft³
Formula
lbf/ft³ = gf/cm³ × 62.42796057614
Derivation from SI units:
- 1 gf/cm³ = 9806.65 N/m³ = 1 tf/m³.
- 1 lbf/ft³ = 4.4482216152605 N ÷ 0.028316846592 m³ ≈ 157.087 N/m³.
- 1 gf/cm³ = 9806.65 N/m³ ÷ 157.0874638462 N/m³ per lbf/ft³ = 62.42796057614 lbf/ft³
Both units are defined exactly, so the factor is exact. Gram-force per Cubic Centimetre definition: gram-force per cubic centimetre; Pound-force per Cubic Foot definition: pound-force per cubic foot.
Worked examples
- A reading of 1.8 gf/cm³ converts to 112.370329 lbf/ft³.
1.8 gf/cm³ × 62.42796058 = 112.370329 lbf/ft³ - A value of 2.65 gf/cm³ is 165.4340955 lbf/ft³.
2.65 gf/cm³ × 62.42796058 = 165.4340955 lbf/ft³
