While determining the location of the tube well, the value of the easting to the left of it (84) is to be written first. Then divide the area upto the next easting into 10 equal parts and find the exact division on which the tube well is located and write it next to the value of easting already found (847). Next write the value of northing just below the tube well along with the easting’s value (84735). Then divide the area upto the next northing into 10 equal parts and find the exact division on which the tube well is located and write it with the values already written (847354). Thus 847354 is the 6 figure grid reference of the tube well.
