A historical Ordnance Survey Map Sheet showing Grid Square HU4590.

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 HU4590 and the vertical and horizontal line divides the square into four quadrants

Dividing the HU4590 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. HU , 45 and 90

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 HU + 45 + 3 + 90 + 5 would give you the six figure grid reference of HU453905

HU4590
HU453905

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!
