The magnitude of gravity near the Earth's surface is approximately 9.81 meters per second squared (m/s²). This value is often rounded to 9.8 m/s² or 10 m/s² for simplicity.

It's important to note that the acceleration due to gravity is not constant everywhere on Earth. It varies slightly depending on factors such as:

* Latitude: Gravity is slightly weaker at the equator than at the poles due to the Earth's rotation.

* Altitude: Gravity decreases as you move further away from the Earth's surface.

* Local geological formations: The density of rocks and minerals beneath the surface can also influence gravity.

However, for most everyday purposes, the standard value of 9.81 m/s² is a good approximation.
