Acceleration Converter
Convert between 8 units of acceleration — m/s², cm/s², ft/s², in/s², standard gravity (g), Gal, milligal, and km/s². Standard gravity is defined as exactly 9.80665 m/s². Formula 1 cars decelerate at over 5 g under maximum braking. The Moon's surface gravity is 1.62 m/s² (1/6 of Earth's). Geophysicists use milligals (mGal) to measure tiny variations in Earth's gravitational field.
About the Acceleration Converter
Acceleration is the rate of change of velocity — how quickly an object speeds up, slows down, or changes direction. The SI unit is metres per second squared (m/s²). Standard gravity (g = 9.80665 m/s²) is defined exactly and is widely used as a unit in aviation, rocketry, and human performance research. The Gal (named after Galileo) is used in geophysics for measuring subtle variations in Earth's gravitational field.
