Acceleration Due to Gravity (Planet, Altitude, Latitude)

Find g for any planet, or adjust Earth's value for altitude and latitude. It uses Newton's law plus the centrifugal correction for rotating bodies.

How to use
  1. Pick a planet, or choose Earth for fine adjustments.
  2. Enter altitude and latitude if you need Earth's local g.
  3. Compare against the IGF80 Earth reference.
For study and estimation. Verify against authoritative data before relying on a result.

Common questions

What is g on Earth?

The standard value is 9.807 m/s2, though it varies slightly with latitude and altitude.

Why does gravity change with latitude?

Earth's rotation produces a centrifugal effect that is strongest at the equator, making measured g a little lower there.
