Formula

Formula
m/s² = in/s² × 0.0254

Multiply any value in inches per second squared by 0.0254 to obtain the value in metres per second squared.

Worked example

Convert 100 in/s² to m/s².

  1. 01Start with 100 in/s².
  2. 02Multiply by the conversion factor: 100 × 0.0254 = 2.54 m/s².
Result100 in/s² = 2.54 m/s²

FAQ

What is the conversion factor from in/s² to m/s²?
1 in/s² equals 0.0254 m/s². To convert, multiply the value in inches per second squared by 0.0254.
How do I convert 1 in/s² to m/s²?
1 in/s² = 0.0254 m/s². For any value, multiply by 0.0254.
How do I convert m/s² back to in/s²?
Divide by the same factor — or equivalently, multiply by 39.37008. So 1 m/s² = 39.3701 in/s².
When would I need to convert inch per second squared to metre per second squared?
Acceleration conversions between in/s² and m/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).
