FAQ

What is the conversion factor from mph/s to g?
1 mph/s equals 0.04558539 g. To convert, multiply the value in miles per hour per second by 0.04558539.
How do I convert 1 mph/s to g?
1 mph/s = 0.0455854 g. For any value, multiply by 0.04558539.
How do I convert g back to mph/s?
Divide by the same factor — or equivalently, multiply by 21.93685. So 1 g = 21.9369 mph/s.
When would I need to convert mile per hour per second to standard gravity?
Acceleration conversions between mph/s and g 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).
