Factor1 mph/s = 1.609344 (km/h)/s

Converter

mph/s

Accepts numbers or expressions, e.g. 150 + 14.7

Result
16.0934(km/h)/s

Rendered to 6 significant figures.

Formula

Formula
(km/h)/s = mph/s × 1.609344

Multiply any value in miles per hour per second by 1.609344 to obtain the value in kilometres per hour per second.

Worked example

Convert 10 mph/s to (km/h)/s.

  1. 01Start with 10 mph/s.
  2. 02Multiply by the conversion factor: 10 × 1.609344 = 16.0934 (km/h)/s.
Result10 mph/s = 16.0934 (km/h)/s

FAQ

What is the conversion factor from mph/s to (km/h)/s?
1 mph/s equals 1.609344 (km/h)/s. To convert, multiply the value in miles per hour per second by 1.609344.
How do I convert 1 mph/s to (km/h)/s?
1 mph/s = 1.60934 (km/h)/s. For any value, multiply by 1.609344.
How do I convert (km/h)/s back to mph/s?
Divide by the same factor — or equivalently, multiply by 0.6213712. So 1 (km/h)/s = 0.621371 mph/s.
When would I need to convert mile per hour per second to kilometre per hour per second?
Acceleration conversions between mph/s and (km/h)/s 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).
