How to Convert Pound per Cubic Foot to Gram per Cubic Centimeter
- 1 lb/ft³ = 0.01601846337 g/cm³
- 1 g/cm³ = 62.42796058 lb/ft³
- Example: convert 15 lb/ft³ to g/cm³: 15 lb/ft³ = 15 × 0.01601846337 g/cm³ = 0.2402769506 g/cm³
Formula
g/cm³ = lb/ft³ × 0.01601846337396
or g/cm³ = lb/ft³ ÷ 62.42796057614
Derivation from SI units:
- 1 lb/ft³ = 0.45359237 kg ÷ 0.028316846592 m³ = 16.018463374 kg/m³
- 1 g/cm³ = 10⁻³ kg ÷ 10⁻⁶ m³ = 1000 kg/m³
- 1 lb/ft³ = 16.01846337396 kg/m³ ÷ 1000 kg/m³ per g/cm³ = 0.01601846337396 g/cm³
Both units are defined exactly, so the factor is exact. Pound per Cubic Foot definition: pound per cubic foot; Gram per Cubic Centimeter definition: gram per cubic centimeter.
Worked examples
- A reading of 30 lb/ft³ converts to 0.4805539012 g/cm³.
30 lb/ft³ × 0.01601846337 = 0.4805539012 g/cm³ - A value of 110 lb/ft³ is 1.762030971 g/cm³.
110 lb/ft³ × 0.01601846337 = 1.762030971 g/cm³
