How to Convert Pound per Cubic Inch to Kilogram per Liter
- 1 lb/in³ = 27.67990471 kg/L
- 1 kg/L = 0.036127292 lb/in³
- Example: convert 15 lb/in³ to kg/L: 15 lb/in³ = 15 × 27.67990471 kg/L = 415.1985707 kg/L
Formula
kg/L = lb/in³ × 27.6799047102
Derivation from SI units:
- 1 lb/in³ = 0.45359237 kg ÷ 1.6387064 × 10⁻⁵ m³ = 27 679.9047 kg/m³
- 1 kg/L = 1 kg ÷ 10⁻³ m³ = 1000 kg/m³ = 1 g/cm³
- 1 lb/in³ = 27679.9047102 kg/m³ ÷ 1000 kg/m³ per kg/L = 27.6799047102 kg/L
Both units are defined exactly, so the factor is exact. Pound per Cubic Inch definition: pound per cubic inch; Kilogram per Liter definition: kilogram per liter.
Worked examples
- A reading of 0.16 lb/in³ converts to 4.428784754 kg/L.
0.16 lb/in³ × 27.67990471 = 4.428784754 kg/L - A value of 0.32 lb/in³ is 8.857569507 kg/L.
0.32 lb/in³ × 27.67990471 = 8.857569507 kg/L

Where it's used
Pounds per Cubic Inch are used for metal densities (steel ≈ 0.284 lb/in³, aluminium ≈ 0.098 lb/in³), while kilograms per liter appear in fuel densities (petrol ≈ 0.74 kg/L, diesel ≈ 0.84 kg/L). Both measure density (mass per unit volume) and mass concentration, so the conversion is a fixed factor.
