FAQ

What is the conversion factor from slug/ft³ to kg/m³?
1 slug/ft³ equals 515.3788 kg/m³. To convert, multiply the value in slugs per cubic foot by 515.3788.
How do I convert 1 slug/ft³ to kg/m³?
1 slug/ft³ = 515.379 kg/m³. For any value, multiply by 515.3788.
How do I convert kg/m³ back to slug/ft³?
Divide by the same factor — or equivalently, multiply by 0.00194032. So 1 kg/m³ = 0.00194032 slug/ft³.
When would I need to convert slug per cubic foot to kilogram per cubic metre?
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).
