Is there a JS library that converts MGRS to LL? I have found one that converts Lat/Lng to MGRS, but nothing that converts MGRS to Lat/Lng.

Someone asked this question in the past, but the answer was USNG to LL but I HAVE to do MGRS to LL.

What about usng.js from

In the library's MGRS to LL function it states

"create a Military Grid Reference System string. this is the same as a USNG string, but with no spaces. space delimiters are optional but allowed in USNG, but are not allowed in MGRS notation. but the numbers are the same."

By that logic, presumably USNG to LL is MGRS to LL.

I should have said this a while ago. I forgot about the open question, but that is what I ended up doing. – Mitchell Ingram Mar 13 '13 at 19:00
