How to Convert Gram per Liter to Pound per Gallon
- 1 g/L = 0.008345404452 lb/gal
- 1 lb/gal = 119.8264273 g/L
- Example: convert 15 g/L to lb/gal: 15 g/L = 15 × 0.008345404452 lb/gal = 0.1251810668 lb/gal
Reference conditions. lb/gal: Per US gallon (231 in³).
Formula
lb/gal = g/L × 0.008345404452019
or lb/gal = g/L ÷ 119.8264273169
Derivation from SI units:
- 1 g/L = 10⁻³ kg ÷ 10⁻³ m³ = 1 kg/m³
- 1 lb/gal = 0.45359237 kg ÷ 0.003785411784 m³ = 119.8264273 kg/m³
- 1 g/L = 1 kg/m³ ÷ 119.8264273169 kg/m³ per lb/gal = 0.008345404452019 lb/gal
Both units are defined exactly, so the factor is exact. Gram per Liter definition: gram per liter; Pound per Gallon definition: pound per gallon.
Worked examples
- A reading of 1.98 g/L converts to 0.01652390081 lb/gal.
1.98 g/L × 0.008345404452 = 0.01652390081 lb/gal - A value of 35 g/L is 0.2920891558 lb/gal.
35 g/L × 0.008345404452 = 0.2920891558 lb/gal

Where it's used
Grams per Liter are used for gas densities (CO₂ ≈ 1.98 g/L at 0 °C), while pounds per gallon appear in drilling-mud weight in the oil and gas industry (ppg). Both measure density (mass per unit volume) and mass concentration, so the conversion is a fixed factor.
