How to Convert Pound-force per Cubic Foot to Gram-force per Cubic Centimetre
- 1 lbf/ft³ = 0.01601846337 gf/cm³
- 1 gf/cm³ = 62.42796058 lbf/ft³
- Example: convert 15 lbf/ft³ to gf/cm³: 15 lbf/ft³ = 15 × 0.01601846337 gf/cm³ = 0.2402769506 gf/cm³
Formula
gf/cm³ = lbf/ft³ × 0.01601846337396
or gf/cm³ = lbf/ft³ ÷ 62.42796057614
Derivation from SI units:
- 1 lbf/ft³ = 4.4482216152605 N ÷ 0.028316846592 m³ ≈ 157.087 N/m³.
- 1 gf/cm³ = 9806.65 N/m³ = 1 tf/m³.
- 1 lbf/ft³ = 157.0874638462 N/m³ ÷ 9806.65 N/m³ per gf/cm³ = 0.01601846337396 gf/cm³
Both units are defined exactly, so the factor is exact. Pound-force per Cubic Foot definition: pound-force per cubic foot; Gram-force per Cubic Centimetre definition: gram-force per cubic centimetre.
Worked examples
- A reading of 110 lbf/ft³ converts to 1.762030971 gf/cm³.
110 lbf/ft³ × 0.01601846337 = 1.762030971 gf/cm³ - A value of 125 lbf/ft³ is 2.002307922 gf/cm³.
125 lbf/ft³ × 0.01601846337 = 2.002307922 gf/cm³
