Converts acceleration between meters per second squared (the SI base unit), feet per second squared, standard gravity (g — the international standard value of 9.80665 m/s², commonly used in engineering and physics), Gal (the CGS unit still used in geophysics/gravimetry), and rate-of-speed-change units like km/h/s and mph/s.
How it works
Enter a value and select the units to convert from and to. Every unit is defined by its exact multiplier relative to meters per second squared, the shared base unit.

Examples
Standard gravity in SI units
1 g (standard gravity) equals exactly 9.80665 m/s² by international definition.
Who should use it
- Converting a vehicle's 0-60 mph acceleration spec into SI units.
- Physics and engineering unit conversions.
Industry applications
- Physics and engineering
- Automotive performance specs
- Geophysics and gravimetry
Advantages
- Covers both everyday (g, m/s², ft/s²) and specialized (Gal) acceleration units.
- Includes rate-of-speed-change units (km/h/s, mph/s) useful for vehicle acceleration specs.
Limitations
- Does not include angular acceleration units (rad/s²), a different physical quantity.
Common mistakes to avoid
- Confusing "g" (standard gravity, a unit of acceleration) with "g" as an abbreviation for grams (a unit of mass) — context matters.
Best practices
- Use g-force units when discussing everyday acceleration experiences (roller coasters, car braking) since they're intuitive relative to felt gravity.
Tips
- For angular acceleration (rotational, not linear) conversions, look for a dedicated angular unit converter instead — this tool covers linear acceleration only.
