In order to use northings and eastings with UTM coordinates, you need to know two things: First, which of those 60 zones you're in; and second, where you are in relation to the central meridian of the zone and where you are in relation to the equator. Latitude is the measurement of distance north or south of the Equator. The sets of lines form small squares called grid squares. Beginning at the bottom, measure up 1 inch and draw a parallel line from left to right on the horizontal. If the data frame's coordinate system is set to the same coordinate system of your easting/northing values, you can set the units of the Go To XY tool to the same unit (aka meters or feet) and search that way. A note of caution: A method also is used that simply adds N or S following the zone number to indicate North or South hemisphere (the easting and northing coordinates along with the zone number supplying everything necessary to geolocate a position except which hemisphere). Convert Latitude and Longitude to State Plane It runs from the South to the North with numbers increasing Eastwards.
