Swissgrid CH1903

If you're dealing with coordinates in Switzerland, you may find it necessary to deal with the Swiss coordinate system known as CH1903. In this case, it can be useful to be able to convert coordinates from this Swiss system (given as a pair of 6-digit integers) into the more generally-used global system known as WGS84 (given as a latitude and longitude in degrees).

This page offers a way to convert Swissgrid coordinates to global coordinates, giving the answers in three formats: Decimal degrees, Degrees and decimal minutes, and degrees, minutes and seconds. These three are all equivalent, it just depends which output format you find most convenient.
