FAQ

What is the conversion factor from kg/m³ to lb/ft³?
1 kg/m³ equals 0.06242796 lb/ft³. To convert, multiply the value in kilograms per cubic metre by 0.06242796.
How do I convert 1 kg/m³ to lb/ft³?
1 kg/m³ = 0.062428 lb/ft³. For any value, multiply by 0.06242796.
How do I convert lb/ft³ back to kg/m³?
Divide by the same factor — or equivalently, multiply by 16.01846. So 1 lb/ft³ = 16.0185 kg/m³.
When would I need to convert kilogram per cubic metre to pound per cubic foot?
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).
