FAQ

What is the conversion factor from in/s² to ft/s²?
1 in/s² equals 0.08333333 ft/s². To convert, multiply the value in inches per second squared by 0.08333333.
How do I convert 1 in/s² to ft/s²?
1 in/s² = 0.0833333 ft/s². For any value, multiply by 0.08333333.
How do I convert ft/s² back to in/s²?
Divide by the same factor — or equivalently, multiply by 12. So 1 ft/s² = 12 in/s².
When would I need to convert inch per second squared to foot per second squared?
Acceleration conversions between in/s² and ft/s² are common in vibration analysis, seismic load calculations, mechanical equipment specifications, and motion-control design. m/s² is the SI standard; g (standard gravity) is widely used in shock, vibration, and ride-quality work.
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).
