This tool will calculate the coordinates from the two 5-digit character/number codes in the open source day1976's Reverse Wherigo.

Also, you can enter coordinates and create these two codes as well. Coordinates may be entered as Degree Decimal Minutes (DMM), Decimal Degrees (DD), or Degrees, Minutes & Seconds (DMS).

Please note: This coordinate format introduces some rounding after the 5th decimal place so you may notice the coordinates changing slightly between different formats in these edge cases.
