FAQ

What is the conversion factor from kg/dm³ to lb/gal?
1 kg/dm³ equals 8.345404 lb/gal. To convert, multiply the value in kilograms per cubic decimetre by 8.345404.
How do I convert 1 kg/dm³ to lb/gal?
1 kg/dm³ = 8.3454 lb/gal. For any value, multiply by 8.345404.
How do I convert lb/gal back to kg/dm³?
Divide by the same factor — or equivalently, multiply by 0.1198264. So 1 lb/gal = 0.119826 kg/dm³.
When would I need to convert kilogram per cubic decimetre 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).
