How to Convert Pound per Gallon to Kilogram per Cubic Meter
- 1 lb/gal = 119.8264273 kg/m³
- 1 kg/m³ = 0.008345404452 lb/gal
- Example: convert 15 lb/gal to kg/m³: 15 lb/gal = 15 × 119.8264273 kg/m³ = 1797.39641 kg/m³
Reference conditions. lb/gal: Per US gallon (231 in³).
Formula
kg/m³ = lb/gal × 119.8264273169
Derivation from SI units:
- 1 lb/gal = 0.45359237 kg ÷ 0.003785411784 m³ = 119.8264273 kg/m³
- 1 kg/m³ = 1 kg ÷ 1 m³
Both units are defined exactly, so the factor is exact. Pound per Gallon definition: pound per gallon; Kilogram per Cubic Meter definition: kilogram per cubic meter.
Worked examples
- A reading of 7.1 lb/gal converts to 850.7676339 kg/m³.
7.1 lb/gal × 119.8264273 = 850.7676339 kg/m³ - A value of 10 lb/gal is 1198.264273 kg/m³.
10 lb/gal × 119.8264273 = 1198.264273 kg/m³
