Online Acceleration Converter

Convert m/s², g-force, ft/s², and km/h². Free tool for physics and engineering.

Acceleration is the rate of change of velocity with respect to time. In the SI, the unit is m/s². The standard gravitational acceleration of Earth is g = 9.80665 m/s² (defined by BIPM). In aviation, fighter pilots withstand up to 9G; astronauts face ≈3G at launch. Smartphone accelerometers measure in m/s². In automotive development, 0–100 km/h in seconds is converted to average m/s². Newton's Second Law: F = m × a (1 Newton = 1 kg × 1 m/s²). This converter covers m/s², g, Gal (cm/s²), ft/s², and km/h².

Frequently Asked Questions

What is the acceleration of gravity in m/s²?

The standard gravitational acceleration is g = 9.80665 m/s² (defined by BIPM).

How do I convert m/s² to g?

Divide by 9.80665. Example: 19.6133 m/s² ÷ 9.80665 = 2g.

What is 1G of force?

1G = 9.80665 m/s². It is the acceleration felt at rest on the Earth's surface.

What is a Gal in acceleration?

1 Gal = 1 cm/s² = 0.01 m/s². Used in geophysics and seismology.
