Petri, unfortunately I cannot test your transformation, but these values are not in the standard format. Longitude ranges from -180 to +180 degrees, so, based on Finland's position, 6010.570 seems to be 60 degrees + 10.570 minutes =  60,176 degrees (60+10.570/60). The same for latitude:  2455.930 -> 24d55.930' = 24,932d (What's this, Helsinki?)

Try this.
hope this helps.

Felipe.
