How to Convert Gram-force per Cubic Centimetre to Pound-force per Cubic Inch
- 1 gf/cm³ = 0.036127292 lbf/in³
- 1 lbf/in³ = 27.67990471 gf/cm³
- Example: convert 15 gf/cm³ to lbf/in³: 15 gf/cm³ = 15 × 0.036127292 lbf/in³ = 0.54190938 lbf/in³
Formula
lbf/in³ = gf/cm³ × 0.03612729200008
or lbf/in³ = gf/cm³ ÷ 27.6799047102
Derivation from SI units:
- 1 gf/cm³ = 9806.65 N/m³ = 1 tf/m³.
- 1 lbf/in³ = 4.4482216152605 N ÷ 1.6387064 × 10⁻⁵ m³ ≈ 271,447 N/m³.
- 1 gf/cm³ = 9806.65 N/m³ ÷ 271447.1375263 N/m³ per lbf/in³ = 0.03612729200008 lbf/in³
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 Inch definition: pound-force per cubic inch.
Worked examples
- A reading of 1.8 gf/cm³ converts to 0.0650291256 lbf/in³.
1.8 gf/cm³ × 0.036127292 = 0.0650291256 lbf/in³ - A value of 2.65 gf/cm³ is 0.0957373238 lbf/in³.
2.65 gf/cm³ × 0.036127292 = 0.0957373238 lbf/in³
