FAQ

What is the conversion factor from ft/s² to in/s²?
1 ft/s² equals 12 in/s². To convert, multiply the value in feet per second squared by 12.
How do I convert 1 ft/s² to in/s²?
1 ft/s² = 12 in/s². For any value, multiply by 12.
How do I convert in/s² back to ft/s²?
Divide by the same factor — or equivalently, multiply by 0.08333333. So 1 in/s² = 0.0833333 ft/s².
When would I need to convert foot per second squared to inch per second squared?
Acceleration conversions between ft/s² and in/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).
