How is a 4-digit map read?

• A. Read as 30, 50
• B. Read as 3, 050
• C. Read as 300, 50
• D. Read as 3, 5-0

Answer: (A)

Reading a four-digit map coordinate uses two digits for eastings and two for northings. The first pair tells you how far to the east, the second pair how far to the north, within the current 100-km grid square. So a coordinate read as 30, 50 places you 30 kilometers east and 50 kilometers north of the grid origin, pinpointing a specific 1-km square on the map. The other formats don’t follow this standard grouping—mixing digits or using an unequal split doesn’t correctly identify the same location.
