How close will a 10 digit grid get you?
The confusion comes in when soldiers try to use a map to get a 10-digit grid coordinate, which equates to a 1 meter precision. A 1:50,000 scale map is only accurate to 50m 90% of the time so a 6 digit (100m precision) or an 8 digit (10m precision) are more appropriate.
How do you plot coordinates on a grid?
How do you write military grid coordinates?
An example of an MGRS coordinate, or grid reference, would be 4QFJ12345678, which consists of three parts: 4Q (grid zone designator, GZD) FJ (the 100,000-meter square identifier) 12345678 (numerical location; easting is 1234 and northing is 5678, in this case specifying a location with 10 m resolution).
How are grid coordinates written?
Coordinates are written along the sides of a map designating specific grid lines. (These grid lines are based on UTM values.) The two larger numbers identify a grid line and are known as principal digits as depicted below. To plot coordinate values, always read right, then up.
