This calculator computes the distance between two points on Earth. It uses the Vincenty formula. The calculator uses the mean radius value according to WGS 84. According to Wikipedia, since Earth is not an ideal sphere, the formula can give a 0.5% error. You can read more here: http://en.wikipedia.org/wiki/Great_circle_distance
