Gal (galileo) quick reference
| Gal (galileo) | Meter per second squared | Standard gravity | Foot per second squared |
|---|---|---|---|
| 1 Gal | = 0.01 m/s² | ≈ 0.001019716213 g₀ | ≈ 0.03280839895 ft/s² |
| 10 Gal | = 0.1 m/s² | ≈ 0.01019716213 g₀ | ≈ 0.3280839895 ft/s² |
| 100 Gal | = 1 m/s² | ≈ 0.1019716213 g₀ | ≈ 3.280839895 ft/s² |
| 1000 Gal | = 10 m/s² | ≈ 1.019716213 g₀ | ≈ 32.80839895 ft/s² |
Where the galileo fits
The next larger acceleration unit is the inch per second squared (in/s²). 1 Gal ≈ 0.3937007874 in/s², and 1 in/s² = 2.54 Gal.
