Inch per second squared quick reference
| Inch per second squared | Meter per second squared | Standard gravity | Gal (galileo) |
|---|---|---|---|
| 1 in/s² | = 0.0254 m/s² | ≈ 0.002590079181 g₀ | = 2.54 Gal |
| 10 in/s² | = 0.254 m/s² | ≈ 0.02590079181 g₀ | = 25.4 Gal |
| 100 in/s² | = 2.54 m/s² | ≈ 0.2590079181 g₀ | = 254 Gal |
| 1000 in/s² | = 25.4 m/s² | ≈ 2.590079181 g₀ | = 2540 Gal |
Where the inch per second squared fits
The next smaller acceleration unit is the galileo (Gal). 1 in/s² = 2.54 Gal, and 1 Gal ≈ 0.3937007874 in/s².
The next larger acceleration unit is the foot per second squared (ft/s²). 1 in/s² ≈ 0.08333333333 ft/s², and 1 ft/s² = 12 in/s².
