Four figure grid references locate a grid square (usually 1 km square) on a map. The four figure grid reference is always given for the bottom left hand corner of the square (the South West corner) and you always write the Eastings
Easting and northing
The terms easting and northing are geographic Cartesian coordinates for a point. Easting refers to the eastward-measured distance (or the x-coordinate), while northing refers to the northward-measured distance (or the y-coordinate).
How many numbers are in a 4 figure grid reference?
A 4-figure grid reference contains 4 numbers. For example, you might be given the number 3422. The first two numbers are called the easting, which is the number you would look for at the bottom of the map. The second two numbers are called the northing and represent the numbers you would look for on the side of the map.
How do you make a four-figure grid reference?
Start at the left-hand side of the map and go east until you get to the bottom-left-hand corner of the square you want. Write this number down. Move north until you get to the bottom-left corner of the square you want. Look at the number of this grid line and add it to the two-digit number you already have. This is your four-figure grid reference.
What is the 4-figure grid reference for 1331?
Your grandfather gives you the 4-figure grid reference 1331. The intersection of these grid lines is the bottom left corner of the square where the surprise is. Looking at the bottom green numbers, you find the easting number 13.
How do you find the Northing on a 4-figure grid?
Your grandfather gives you the 4-figure grid reference 1331. The intersection of these grid lines is the bottom left corner of the square where the surprise is. Looking at the bottom green numbers, you find the easting number 13. Then you move up (northward) to the horizontal red line representing the purple number 31, which is the northing.

What is the difference between 4 figure grid referencing and 6 figure grid?
What is the difference between four-figure and six-figure grid references? Four-figure grid references are used to find a grid square but we can use six-figure grid references to find an exact location within a grid square. Six-figure grid references are much more accurate than four-figure grid references.
What is use of four figure and six figure grid reference?
Four-figure grid reference: Square grid or four-figure grid reference e.g., the four figure grid reference of A in the figure is 6218. It means that A lies between Eastings 62 to 63 and Northings 18 to 19. Six-figure grid reference: The six figure grid reference gives the exact location of a feature.
What is an advantage of using a 6-figure grid reference rather than a 4-figure grid reference?
Comparatively bigger geographic features are located through 4-figure grid reference. Eg: lake, fort, etc. Comparatively smaller geographic features are generally located through 6-figure grid reference method.
How do I find the grid reference for my house?
Google MapsClick "Grid Reference Tools" and choose "Get Grid Reference from Map". By clicking on the desired location, the 6-figure Grid reference will be shown. ... Click "Location Search Tools" and enter a place name (this does not work with post codes). The map will centre on the place name, if found.
What is 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.
What is the purpose of grid references?
A grid reference is a location on a map, which is found using the northing and easting numbered lines. Grid references are useful for helping a map user to find specific locations.
What is importance of six figure grid reference?
With the help of this six-digit number we not only can identify the exact location but also the exact point on the map. Six square grid reference gives us an accurate location.
What is a 6 figure grid references?
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.
Why is a six figure grid reference more useful how is it determined?
In six-figure grid square method after getting the four figures again, easting and northings are divided into ten equal parts and both easting and northing subdivision numbers are taken out. With the help of this six-digit number we not only can identify the exact location but also the exact point on the map.
How accurate is a six figure grid reference?
What is the accuracy of a 6 figure grid reference? A 6 figure grid reference will cover an area of 100m by 100m, i.e. 10,000 square meters, an area bigger than Wembley football pitch.
What does the six figure grid reference 198823 tell you?
What does the six-figure grid reference 198823 tell you? It gives you an exact point in grid square 1988 that is 2/10s up and 3/10s along. It gives you an exact point in grid square 1988 that is 2/10s across and 3/10s up.
What is grid reference?
Grid references. A grid of squares helps the map-reader to locate a place. The vertical lines are called eastings. They are numbered - the numbers increase to the east. The horizontal lines are called northings as the numbers increase in an northerly direction.
Where do you start the squares on a map?
Start at the left-hand side of the map and go east until you get to the bottom-left-hand corner of the square you want. Write this number down.
