About acceleration units
Acceleration is the rate of change of velocity. Its SI unit is the meter per second squared (m/s²): an increase in speed of one meter per second every second.
Accelerations are often given as multiples of standard gravity, g₀, defined as exactly 9.80665 m/s² (about 32.174 ft/s²). Geophysics uses the gal, exactly 0.01 m/s², and the milligal for small differences in gravity.
Frequently asked questions
- What does "1 g" mean in m/s²?
- One standard gravity, exactly 9.80665 m/s², or about 32.174 ft/s². "5 g" means five times that acceleration.
- Is standard gravity the same as gravity everywhere on Earth?
- No. Standard gravity is a fixed reference value. Actual gravity varies with latitude and altitude, from about 9.78 m/s² at the equator to about 9.83 m/s² at the poles.
- How many feet per second squared are in one meter per second squared?
- One meter per second squared ≈ 3.280839895 ft/s² (feet per second squared).
- How many standard gravities are in one meter per second squared?
- One meter per second squared ≈ 0.1019716213 g₀ (standard gravities).
