FAQ

What is the conversion factor from slug/ft³ to SG?
1 slug/ft³ equals 0.5153788 SG. To convert, multiply the value in slugs per cubic foot by 0.5153788.
How do I convert 1 slug/ft³ to SG?
1 slug/ft³ = 0.515379 SG. For any value, multiply by 0.5153788.
How do I convert SG back to slug/ft³?
Divide by the same factor — or equivalently, multiply by 1.94032. So 1 SG = 1.94032 slug/ft³.
When would I need to convert slug per cubic foot to specific gravity (water)?
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).
