Direction

choose which way to convert

Latitude

decimal degrees; −80 to 84

Longitude

decimal degrees; −180 to 180

digits after the 100 km square, per easting and northing

MGRS reference

zone, band, 100 km square and two equal digit groups — spaces optional

WGS84 and UTM only, from 80°S up to 84°N. Easting and northing digits are truncated, not rounded, so a reference always names the same square every time. Datum shifts are not applied.
