Question 1

What is Earth's surface gravity?

Accepted Answer

Earth's standard gravity is 9.80665 m/s² (1g). It varies slightly by location, from 9.78 at the equator to 9.83 at the poles.

Question 2

Why does gravity vary on Earth?

Accepted Answer

Earth's rotation, non-spherical shape, and local mass concentrations cause variations of about ±0.5% from the standard value.

Question 3

Is this conversion exact or approximate?

Accepted Answer

This conversion uses the precise mathematical formula and is exact for standard conditions. For gravitational acceleration, values may vary slightly by location.

Question 4

What is the standard gravity value used?

Accepted Answer

Standard gravity (g) is defined as exactly 9.80665 m/s². This value is used as the reference for acceleration conversions involving g-force.
