Formula

Formula
cm/s² = (km/h)/s × 27.77778

Multiply any value in kilometres per hour per second by 27.77778 to obtain the value in centimetres per second squared (Gal).

Worked example

Convert 1 (km/h)/s to cm/s².

  1. 01Start with 1 (km/h)/s.
  2. 02Multiply by the conversion factor: 1 × 27.77778 = 27.7778 cm/s².
Result1 (km/h)/s = 27.7778 cm/s²

FAQ

What is the conversion factor from (km/h)/s to cm/s²?
1 (km/h)/s equals 27.77778 cm/s². To convert, multiply the value in kilometres per hour per second by 27.77778.
How do I convert 1 (km/h)/s to cm/s²?
1 (km/h)/s = 27.7778 cm/s². For any value, multiply by 27.77778.
How do I convert cm/s² back to (km/h)/s?
Divide by the same factor — or equivalently, multiply by 0.036. So 1 cm/s² = 0.036 (km/h)/s.
When would I need to convert kilometre per hour per second to centimetre per second squared (Gal)?
Acceleration conversions between (km/h)/s and cm/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).
