How to Convert Acceleration Units
Acceleration is the rate of change of velocity. The SI unit is metre per second squared (m/s²); vibration and shock are often expressed in g, where standard gravity is exactly 9.80665 m/s².
Every unit on this page is stored as a fixed factor relative to one reference unit, the metre per sq second (m/s²). Converting is a two step multiply and divide:
- Multiply your value by the factor of the source unit to get the value in m/s².
- Divide that result by the factor of the target unit.

Frequently Asked Questions
What is the SI unit of acceleration?
The SI unit of acceleration is the metre per sq second (m/s²). Acceleration is the rate of change of velocity.
How do I convert standard gravity to m/s²?
To convert standard gravity (g) to metre per sq second (m/s²), multiply the value in standard gravity by 9.80665. For example, 1 g = 9.80665 m/s².
How do I convert m/s² to standard gravity?
To convert metre per sq second (m/s²) to standard gravity (g), multiply the value in m/s² by 0.101972. For example, 1 m/s² = 0.101972 g.
How do I convert ft/s² to m/s²?
To convert foot per sq second (ft/s²) to metre per sq second (m/s²), multiply the value in ft/s² by 0.3048. For example, 1 ft/s² = 0.3048 m/s².
Can I see a value in every acceleration unit at once?
Yes. Enter a value and choose the source unit; the "all units" table below the converter instantly lists the equivalent in all 10 supported units. Click any row to make it the target unit.
