How many digits are in a grid coordinate?
100,000-meter Square Identification (i.e. UJ ). Grid coordinates of some even number of digits ranging from 2 to 10 (i.e. 23480647 In this case, eight digits identify a place of about the size of a modest home.). You always read right, then up when plotting coordinates.
How accurate is a 4 digit grid coordinate?
4 digits – 2306 – locates a point with a precision of 1,000-meters (a neighborhood size area). 6 digits – 234064 – locates a point with a precision of 100-meters (a soccer field size area). 8 digits – 23480647 – locates a point with a precision of 10-meters (the size of a modest home).
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 do you read a 4 digit grid?
An easy way to remember this is that to get the first number, you go along the corridor (horizontal, x axis, eastings) and then up the stairs (vertical, y axis, northings). For example, the number 2 in the diagram below is square 19 across and square 45 up and therefore, the four-figure grid reference is ‘1945’.

How close does a 4 digit grid get you?
1000 meters
Remember, four-digit grids get you to within 1000 meters, six-digit grids to within 100 meters and an eight-digit grid gets us to within 10 meters.
How do I get the 10 digit grid on Google Maps?
To use Google Maps position the map and, using the zoom tool on the left-hand side of the screen, zoom in to the maximum level to find the place for which you want a Grid Reference. Then either: Click “Grid Reference Tools” and choose “Get Grid Reference from Map”.
How close does a 8 digit grid get you?
10 meters
How close is a 10 digit grid coordinate?
How accurate is a 10 digit grid?
What is the six digit grid coordinate for 100 meters?
On the bottom scale, the 100 meter mark nearest the vertical grid line provides the third digit, 5. On the vertical scale, the 100 meter mark nearest Point A provides the sixth digit, 3. Therefore, the six-digit grid coordinate is 115813.
How are the coordinates of a grid square calculated?
The lines that form grid squares are numbered along the outside edge of the map picture. No two grid squares have the same number. 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 the first digit of the coordinates?
The number of the vertical grid line on the left (west) side of the grid square is the first and second digits of the coordinates. The number of the horizontal grid line on the bottom (south) side of the grid square is the fourth and fifth digits of the coordinates.
How are grid coordinates used in real life?
Coordinates are always given as an even number of digits so you know where to separate the easting and northing coordinates. This allows you to abbreviate to the degree of precision you require within a local area. Grid coordinates are used to define point features, such as a neighborhood, soccer field, a particular house, or even a parking place.
