How accurate is a 6 digit grid coordinate?
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 accurate is a 10 figure grid?
Geograph will accept grid references with as little precision as the grid square itself, i.e. 4 figures, or up to 10 figures, which would theoretically locate a feature on the ground with a precision of a 1 metre by 1 metre square.
What is a 6-figure reference?
National Grid reference numbers There are two main types of grid reference: four-figure grid reference, such as ’19 45′, indicates a 1 km by 1 km square on the map; and. six-figure grid reference, such as ‘192 454’, indicates a 100 m by 100 m square on the map.
What is the distance between grid lines on a map?
Using Four-Digit Grid Coordinates to Determine a Location Because grid zones are not manageable in size when navigating, the mapmakers further break down each grid zone into 100,000-meter squares to make the grid zones more manageable. This means that the distance between each grid line is 100,000 meters.
What do the six digit coordinates on a map tell you?
The precision of a point location is shown by the number of digits in the coordinates: the more digits, the more precise the location. 1996-a 1,000 meter grid square.
Which is an example of a six digit grid reference?
Since the map is a new edition map and uses the MGA reference system, the six-digit grid reference is ‘Hilltop MGA-477060’. Example 3: Hill 2122. The hill lies on a grid line meaning that for a six-digit grid reference, the Easting has to include a zero at the end. Hence the six-digit grid reference of Hill 2122 is 010977.
What is the accuracy of a six figure grid reference?
A six figure coordinate has six figure grid reference an accuracy of 100 m2, indicated in the orange square box. This area of error is much smaller than the search area provided by a four-digit grid reference.
How big is a six digit grid coordinate?
For example, a four digit grid coordinate will put you in a 1,000 meter grid square. A six digit grid will put you within a 100 meters of your position (or target), etc. What is a six figure grid references? 6 digit number on a grid Plotting a six-digit grid coordinate will get you within how many meters of the point you wish to identify?
How to get an 8 figure grid reference?
In order to obtain an 8 figure grid reference, you need to carry out the exact same procedure to obtain a 6 figure grid reference, dividing your grid square into tenths, but then further sub-divide the 6 figure tenth in which your location lies into further tenths (the 8 figure tenths).
