The Acceleration Due to Gravity at an Altitude calculator estimates the acceleration due to gravity on Earth at a specific altitude above sea level.
INSTRUCTIONS: Choose units and enter the following:
Acceleration Due to Gravity (galt): The calculator returns the acceleration in meters per second squared. However, this can be automatically converted to compatible units via the pull-down menu.
Theformula computes the approximate acceleration due to gravity on the surface of the Earth based on the altitude. The is:
`g_"alt" = g * ( r_e/(r_e +h))^2`
