Each grid zone is a 6° x 8° container

MGRS 100km Grid

Grid zones are further divided by 100km x 100km squares. Additional digits give greater precision ranging from 10km x 10km to 1m x 1m.

As users zoom into the map, lines will automatically adjust to the next precise step, adding additional digits.

To read MGRS coordinates, move horizontally left to right, then vertically upwards.
