Based in the South West English Region.

The SU2092 square kilometre intersects with the settlement of Highworth.

SU2092 is within the post town of Swindon, Wiltshire.

The square is within Swindon council.

The Point of Origin (0,0) is 461.81 Kilometres away. This is where the National Grid starts around 80 kilometres west of the Isles of Scilly.

This extract is taken from the Ordnance Survey six-inch to the mile series surveyed from 1888-1913. The scale is 1:10,560.

The Square overlayed over the map represents the extent of SU2092 and the vertical and horizontal line divides the square into four quadrants

Dividing the SU2092 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. SU , 20 and 92

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 SU + 20 + 3 + 92 + 5 would give you the six figure grid reference of SU203925

SU	20		92
SU	20	3	92	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!
