Example 2
Find the UTM reference for the NE corner of Neenah, WI, USGS quadrangle
(7.5 minute).
Geographic coordinates (read from map corner):
A. Setup
 Zone number: 88° ÷ 6 = 14.7,
rounding downward 14.7 becomes 14
3014 = 16 (zone number).
 Central meridian for zone 16: 87°
 Angular difference (AD)
point 88° 22' 30"
CM 87 00 00

AD 1 22 30
B. UTM Determination
 Locate table for Lat. = 44° 15' 00" (see figure 17)
 Locate line for = 1° 22' 30" (AD)
 Point is west of CM (88° 22' 30" is greater than 87°)
 Easting (from table) = 390, 221.1 meters
rounded to: 390,220 meters (10meter precision)
 Northing (from table) = 4,900,343.2 meters
rounded to: 4,900,340 meters (10meter precision)
C. Result: UTM reference = Z16E390221 N4900340.
