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

Where it's used
Pounds per Cubic Foot are used for concrete, soil and aggregate densities (normal concrete ≈ 145–150 pcf), 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.
