How to Convert Gram per Cubic Centimeter to Pound per Cubic Foot
- 1 g/cm³ = 62.42796058 lb/ft³
- 1 lb/ft³ = 0.01601846337 g/cm³
- Example: convert 15 g/cm³ to lb/ft³: 15 g/cm³ = 15 × 62.42796058 lb/ft³ = 936.4194086 lb/ft³
Formula
lb/ft³ = g/cm³ × 62.42796057614
Derivation from SI units:
- 1 g/cm³ = 10⁻³ kg ÷ 10⁻⁶ m³ = 1000 kg/m³
- 1 lb/ft³ = 0.45359237 kg ÷ 0.028316846592 m³ = 16.018463374 kg/m³
- 1 g/cm³ = 1000 kg/m³ ÷ 16.01846337396 kg/m³ per lb/ft³ = 62.42796057614 lb/ft³
Both units are defined exactly, so the factor is exact. Gram per Cubic Centimeter definition: gram per cubic centimeter; Pound per Cubic Foot definition: pound per cubic foot.
Worked examples
- A reading of 1.05 g/cm³ converts to 65.5493586 lb/ft³.
1.05 g/cm³ × 62.42796058 = 65.5493586 lb/ft³ - A value of 4.5 g/cm³ is 280.9258226 lb/ft³.
4.5 g/cm³ × 62.42796058 = 280.9258226 lb/ft³
