What does 4-digit grid coordinates represent in meters?

• A. 100 meters
• B. 1000 meters
• C. 10 meters
• D. 10000 meters

Answer: (B)

Four-digit grid coordinates pinpoint a location at kilometer-level precision. The first two digits give the easting in whole kilometers, and the next two give the northing in whole kilometers. Together, they identify a single square that is 1 kilometer by 1 kilometer in size. That means the area represented is 1,000 meters on each side, hence the correct meaning is 1,000 meters. If you need finer accuracy, you’d add more digits to get smaller subdivisions (for example, six digits for 100-meter precision).
