Formula

Formula
m/s² = mph/s × 0.44704

Multiply any value in miles per hour per second by 0.44704 to obtain the value in metres per second squared.

Worked example

Convert 10 mph/s to m/s².

  1. 01Start with 10 mph/s.
  2. 02Multiply by the conversion factor: 10 × 0.44704 = 4.4704 m/s².
Result10 mph/s = 4.4704 m/s²

FAQ

What is the conversion factor from mph/s to m/s²?
1 mph/s equals 0.44704 m/s². To convert, multiply the value in miles per hour per second by 0.44704.
How do I convert 1 mph/s to m/s²?
1 mph/s = 0.44704 m/s². For any value, multiply by 0.44704.
How do I convert m/s² back to mph/s?
Divide by the same factor — or equivalently, multiply by 2.236936. So 1 m/s² = 2.23694 mph/s.
When would I need to convert mile per hour per second to metre per second squared?
Acceleration conversions between mph/s and m/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).
