The Maidenhead Locator System is used to divide the world up into grid squares, identified by a four-character or six-character grid square locator. This form allows you to enter either a grid square locator or the latitude and longitude of a location. If you enter a grid square and select Convert to Lat/Lon, the latitude and longitude fields will be filled in with the postion of the center of the grid square.
