Formula

Formula
(km/h)/s = ft/s² × 1.09728

Multiply any value in feet per second squared by 1.09728 to obtain the value in kilometres per hour per second.

Worked example

Convert 10 ft/s² to (km/h)/s.

  1. 01Start with 10 ft/s².
  2. 02Multiply by the conversion factor: 10 × 1.09728 = 10.9728 (km/h)/s.
Result10 ft/s² = 10.9728 (km/h)/s

FAQ

What is the conversion factor from ft/s² to (km/h)/s?
1 ft/s² equals 1.09728 (km/h)/s. To convert, multiply the value in feet per second squared by 1.09728.
How do I convert 1 ft/s² to (km/h)/s?
1 ft/s² = 1.09728 (km/h)/s. For any value, multiply by 1.09728.
How do I convert (km/h)/s back to ft/s²?
Divide by the same factor — or equivalently, multiply by 0.9113444. So 1 (km/h)/s = 0.911344 ft/s².
When would I need to convert foot per second squared to kilometre per hour per second?
Acceleration conversions between ft/s² 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).
