The latitude measures positions on the earth from south—north and has the equator as 0°. It ranges from 0° to 90°.
The longitude measures positions on the earth from east—west and it is measured as the angle east or west from the Prime Meridian, ranging from 0° at the Prime Meridian to +180° eastward and −180° westward.
Since longitude on earth is maximum 180°, it therefore means that a longitude of 185A°E is NOT contained within earth's system of latitude and longitude.
