(Determining A Location)

Remember this rule: "READ RIGHT and UP".

The grid coordinates of the RED X in the YELLOW GRID SQUARE
are 906643.

Break the coordinates into two even parts like: 906 – 643

Use the first two numbers of each group (90 – 64) to locate the LOWER LEFT point of the GRID SQUARE by using the NUMBERED LINES. Use the rule READ RIGHT and UP.

Now, use the last number of each group (6 – 3) to refine the exact location. (6/10 of the grid square to the RIGHT and 3/10 of the grid square UPWARD) Use the rule READ RIGHT and UP.

NOTES: Each Grid Square is 1000 meters x 1000 meters (1 square kilometer). A kilometer is approximately 6/10 of a mile. Army slang for a kilometer is "a klick".
