This page accepts one input and generates several outputs.  If you input a Grid, the Lat/Lon for the center of the grid will be generated in both decimal and Degree/Minute/Second formats.  If you input a Lat/Lon in either a decimal or DMS format, the other format will be generated, along with the Grid for the input coordinates.  


This page uses a database of U.S. 5-digit zipcodes.  The zipcode that is closest to the center of the grid is selected.  


The Wikipedia entry on the Maidenhead Grid System is the source of the formulas and information used for this page.  Most of the time the grid system uses only two or three pairs to achieve the desired level of accuracy.  Three pairs will indicate an area a bit smaller than 3 miles by by 6.  This converter supports up to 5 pairs for the grid identifier, which yields an area about the size of a football field.
