How to Convert Gram per Cubic Centimeter to Pound per Cubic Inch
- 1 g/cm³ = 0.036127292 lb/in³
- 1 lb/in³ = 27.67990471 g/cm³
- Example: convert 15 g/cm³ to lb/in³: 15 g/cm³ = 15 × 0.036127292 lb/in³ = 0.54190938 lb/in³
Formula
lb/in³ = g/cm³ × 0.03612729200008
or lb/in³ = g/cm³ ÷ 27.6799047102
Derivation from SI units:
- 1 g/cm³ = 10⁻³ kg ÷ 10⁻⁶ m³ = 1000 kg/m³
- 1 lb/in³ = 0.45359237 kg ÷ 1.6387064 × 10⁻⁵ m³ = 27 679.9047 kg/m³
- 1 g/cm³ = 1000 kg/m³ ÷ 27679.9047102 kg/m³ per lb/in³ = 0.03612729200008 lb/in³
Both units are defined exactly, so the factor is exact. Gram per Cubic Centimeter definition: gram per cubic centimeter; Pound per Cubic Inch definition: pound per cubic inch.
Worked examples
- Copper at 8.96 g/cm³ is 0.3237005363 lb/in³.
8.96 g/cm³ × 0.036127292 = 0.3237005363 lb/in³ - A 1.2 g/cm³ plastic is 0.0433527504 lb/in³.
1.2 g/cm³ × 0.036127292 = 0.0433527504 lb/in³
