FAQ

What is the conversion factor from lb/gal to g/L?
1 lb/gal equals 119.8264 g/L. To convert, multiply the value in pounds per US gallon by 119.8264.
How do I convert 1 lb/gal to g/L?
1 lb/gal = 119.826 g/L. For any value, multiply by 119.8264.
How do I convert g/L back to lb/gal?
Divide by the same factor — or equivalently, multiply by 0.008345404. So 1 g/L = 0.0083454 lb/gal.
When would I need to convert pound per US gallon to gram per litre?
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).
