Formula

Formula
in/s² = mph/s × 17.6

Multiply any value in miles per hour per second by 17.6 to obtain the value in inches per second squared.

Worked example

Convert 1 mph/s to in/s².

  1. 01Start with 1 mph/s.
  2. 02Multiply by the conversion factor: 1 × 17.6 = 17.6 in/s².
Result1 mph/s = 17.6 in/s²

FAQ

What is the conversion factor from mph/s to in/s²?
1 mph/s equals 17.6 in/s². To convert, multiply the value in miles per hour per second by 17.6.
How do I convert 1 mph/s to in/s²?
1 mph/s = 17.6 in/s². For any value, multiply by 17.6.
How do I convert in/s² back to mph/s?
Divide by the same factor — or equivalently, multiply by 0.05681818. So 1 in/s² = 0.0568182 mph/s.
When would I need to convert mile per hour per second to inch per second squared?
Acceleration conversions between mph/s 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).
