Percent difference is the difference between two values divided by the average of the two values times 100.

The acceleration due to gravity at sea level is #"9.78719 m/s"^2#.
The acceleration due to gravity at the top of Mount Everest is #"9.766322 m/s"^2#. http://www.physicsclassroom.com/class/1DKin/Lesson-5/Acceleration-of-Gravity

Average = (#"9.78719 m/s"^2 + "9.766322 m/s"^2"#)#/##"2"# = #"9.77676m/s"^2#

Percent difference = (#"9.78719 m/s"^2 - "9.766322 m/s"^2"#)#-:##"9.77676m/s"^2# x #"100"# = #"0.21347%"#
