// How to use
  1. 01Type or paste the position into the box. Any format works, and you don't pick one.
  2. 02Check the black status chip. It says how the tool read your entry, for example "Read as DMS".
  3. 03Read any yellow note. It means the tool assumed something, like West. Confirm it with the caller.
  4. 04Read off whichever format the caller, unit or system needs: DDM, DMS or decimal degrees.
  5. 05Press Copy next to any format, or press Enter to copy DDM.
  6. 06If the result turns red, nothing is shown and nothing can be copied. Fix the entry as the message says.

Works with symbols or without them, commas or colons, letters before or after the numbers (N42 or 42N), words like "north" and "deg", and minus signs for South and West.
