Dividing the SH9301 Square to get a six figure Grid Reference
A helpful reminder for calculating grid references is across the landing and up the stairs.
For example if your house was located in a square that in the fourth square across and sixth square up and you wanted to work out its six figure grid refence.
First, You would divide the four figure grid reference into three parts. SH , 93 and 01
Count across starting with zero. This would give you three. Make a note that X for Across (A Cross) = 3.
Count up starting with zero. This would give you five. Make a note that Y = 5.
So to put it together SH + 93 + 3 + 01 + 5 would give you the six figure grid reference of SH933015
| SH | 93 | 01 | ||
| SH | 93 | 3 | 01 | 5 |
A six figure grid reference would be accurate to 10 metres. To achieve a greater level of accuracy this 10 metre square would be divided into a grid 10 by 10 and the process repeated.
This would produce an 8 figure grid reference that would be accurate to a square metre!
