Geopotential altitude is a vertical coordinate referenced to Earth’s mean sea level. It is an adjustment to geometric altitude, which is the altitude as measured from the mean sea level. Geopotential altitude accounts for the variation of gravity with latitude and altitude. ‘R ’ is the radius of earth and ‘hG’ is the geometric altitude
