FAQ

What is the conversion factor from g/L to lb/gal?
1 g/L equals 0.008345404 lb/gal. To convert, multiply the value in grams per litre by 0.008345404.
How do I convert 1 g/L to lb/gal?
1 g/L = 0.0083454 lb/gal. For any value, multiply by 0.008345404.
How do I convert lb/gal back to g/L?
Divide by the same factor — or equivalently, multiply by 119.8264. So 1 lb/gal = 119.826 g/L.
When would I need to convert gram per litre to pound per US gallon?
Density conversions are critical for fluid property datasheets, hydraulic head calculations, and reconciling lab measurements (often g/cm³) with process simulator inputs (kg/m³).
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
