Convert an Irish Grid Reference to Longitude/Latitude
This can be a 6, 8 or 10 figure grid reference. Please enter leading zeros for padding.

This can be in the form of degrees, minutes and seconds or you can just enter a decimal value for the degrees. Note that all of Ireland is 'West' so enter this value as a positive one.
