Why might you want to use a six-figure grid reference instead of a four-figure

Answer:
6-Figure Grid Reference
A 6-figure grid reference contains 6 numbers which gives us an even more precise location inside the box given by the 4-figure number. Inside each box, imagine 10 tick marks along the eastings and 10 tick marks along the northings. These marks are generally not provided on maps. Let's interpret a 6-figure number, 344223.
The first two numbers are the easting, which is the same as in the 4-number grid. The third number represents how many tenths you need to move east from the easting value. In our 6-number example, our third number is 4, which represents four-tenths more to the east. In other words, go east just shy of half-way to the next easting.
The fourth and fifth numbers are the northing value, which is the same as in the 4-number grid. The last number represents how many tenths you need to move north from the northing location given. In our 6-number example, the last number is 3 which represents 3/10 more to the north of the northing value. In other words, go north roughly a third of the way to the next grid line.
