However, in most cases this won't be a serious problem. Look here for the equations and an online JavaScript applet that will do distance calculations. The accuracy of this calculation depends on the accuracy of the longitude and latitude coordinates. Earth's circumference is about 40,000 km.So 1 of longitude at the equator, or 1 of latitude, is about 40,000/360 = 110 km.So, if you know a site's latitude to only the nearest degree, you know its north-south location only to within about 100 km.n my own work, the question came up recently when I needed to know the distance between two instruments that were measuring insolation (total solar energy arriving at a horizontal surface on the ground) at sites separated by several kilometers.
