The Earthpoint Coordinate Converter takes a geographic position in latitude/longitude, or in a number of grid coordinate systems, including:
- UTM
- MGRS/USNG and MGRS Polar
- GeoRef
and converts it to all the other coordinate systems (including lat/long in decimal, DDMM and DDMMSS formats):

(Grid North is the deviation between true north and north along the map projection grid lines)
You also have the option of viewing the point in Google Earth, with a pop-up balloon that includes all the coordinate data:
