Gravity of Earth

The Acceleration due to Earth Gravity (g_(Earth)) constant is 9.80665 m/s².  This is the acceleration due to gravity on the surface of the Earth at sea level.   This is also known as Standard Gravity. The default units are meters per seconds squared but can be changed on the fly via the pull-down menu to feet per seconds squared and other acceleration units.
