The algorithm is absolutely trivial -> https://en.wikipedia.org/wiki/Military_Grid_Reference_System

It's actually quite pleasant to use and allows you to just truncate to the level of precision you want. S/He just posted the 1m resolution string when 18-SU-J-216-044 would get you to 100m.

All this said, I think the real issue is that we refuse to PICK a standard and so every device with a GPS and ever map has one or two of

-MGRS

-UTM (almost identical to MGRS)

-LL DD MM' SS.ss"

-LL DD.dddd...

-LL DD MM.mmmm...'

etc.

If you make a device that can output or accept a location string, make sure it can handle all LL cases and UTM/MGRS.

I think we have different definitions of trivial. Or you put a lot of trust in the average persons intelligence or more importantly laziness.
