On a map, a six-figure grid reference identifies location within what size square?

• A. A precise location within a 100-meter square
• B. An entire grid zone
• C. A single coordinate value
• D. A map legend

Answer: (A)

Six-figure grid references give you a location to about 100-meter accuracy. The first two digits show the easting within the 1-kilometer square, the next two digits show the northing within that same 1 km square, and the final two digits subdivide that 1 km square into a 100 m by 100 m block. So the reference points you to a precise 100 m square, rather than to an entire grid zone or a single coordinate value or a map legend.
