A 6-digit grid coordinate provides accuracy to the nearest which value?

A 6-digit grid coordinate provides accuracy to the nearest which value?

• A. Nearest 1000 square meters
• B. Nearest 100 square meters
• C. Nearest 10 square meters
• D. Nearest 1 square meter

Answer: (B)

Understanding grid reference precision is key. In a grid system, each pair of digits adds a level of detail: a 4‑digit reference pins you to a 1,000‑meter by 1,000‑meter square, a 6‑digit reference pins you to a 100‑meter by 100‑meter square. That means a 6‑digit grid coordinate locates a point within a 100-meter cell, giving you about 100 meters of accuracy in both the east–west and north–south directions. If you think in terms of area, that 100 m square covers about 10,000 square meters. So the precision is to the nearest 100 meters, i.e., within a 100 m by 100 m grid cell.
