Standard gravity to Metre per second squared

Exact answer: 1 g = 9.80665 m/s² (exact defined constant)

The conversion from Standard gravity to Metre per second squared rests on an exactly defined constant rather than on a measurement. Acceleration appears in physics, vehicle engineering and sensor datasheets.

Examples

010.5 g = 4.903325 m/s²

Example value from the reference table. Internal calculation uses stored factors; display output is rounded.

02Common mistake

Lower-case g as acceleration (9.80665 m/s²) is not the gram. In engineering g usually means standard gravity; in commerce it means gram.

03Base unit: m/s²

1 g = 9.80665 m/s². Then the value is converted through the base unit m/s² into Metre per second squared.
