Formula

Formula
cm/s² = in/s² × 2.54

Multiply any value in inches per second squared by 2.54 to obtain the value in centimetres per second squared (Gal).

Worked example

Convert 10 in/s² to cm/s².

  1. 01Start with 10 in/s².
  2. 02Multiply by the conversion factor: 10 × 2.54 = 25.4 cm/s².
Result10 in/s² = 25.4 cm/s²

FAQ

What is the conversion factor from in/s² to cm/s²?
1 in/s² equals 2.54 cm/s². To convert, multiply the value in inches per second squared by 2.54.
How do I convert 1 in/s² to cm/s²?
1 in/s² = 2.54 cm/s². For any value, multiply by 2.54.
How do I convert cm/s² back to in/s²?
Divide by the same factor — or equivalently, multiply by 0.3937008. So 1 cm/s² = 0.393701 in/s².
When would I need to convert inch per second squared to centimetre per second squared (Gal)?
Acceleration conversions between in/s² 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).
