The acceleration converter allows you to convert between different units of acceleration, which measure the rate of change of velocity. This tool is useful for physics, engineering, mechanics, and many fields where motion is analyzed. Acceleration is a vector quantity representing how quickly an object changes its velocity.
Common Acceleration Measurement Systems
Metric System (SI)
The International System of Units (SI) uses meters per second squared (m/s²) as the standard unit of acceleration.
- Meter per second squared (m/s²): The standard SI unit
- SI prefixes can be used to create multiples and submultiples: mm/s², km/s², etc.
Imperial/US Customary System
Units based on feet, inches, yards, and miles.
- Foot per second squared (ft/s²): Common in engineering in the United States
- Inch per second squared (in/s²): Used for small-scale acceleration measurements
- Yard per second squared (yd/s²): Less commonly used
- Mile per second squared (mi/s²): Used for very large accelerations
Gravitational Units
Units based on the Earth's gravitational acceleration.
- Standard gravity (g): Equal to 9.80665 m/s², often used in aviation and aerospace
CGS System
The Centimeter-Gram-Second system uses the gal (or galileo) as its acceleration unit.
- Gal (Gal): Equal to 1 cm/s²
- Milligal (mGal): 1/1000 of a gal, used in geophysics and geodesy
- Microgal (µGal): 1/1,000,000 of a gal, used in high-precision measurements
Other Units
Specialized units for specific applications.
- Knot per second (kn/s): Rate of change of speed in nautical miles per hour per second
