  1. Six-Figure Grid References Modified for the 142 St. Andrew’s College Highland Cadet Corps.

  2. Now that you have an understanding of how to use four-figure grid referencing, six-figure grid referencing will be very easy to learn. There is only one additional step to the process, yet it makes your coordinates significantly more accurate.

  3. A four figure reference will point you to a square on the map. • Six figure grid references are used to pin point a location within a square. • It is important to be able to find details given by a six-figure grid reference as well as being able to work out the six-figure grid reference for any point on the map.

  4. How to work out 6 figure grid references… • Let us first look at how the 6 figure grid reference is shown: • Let’s take 216 322 as an example. • The first 3 figures refer to the easting of the point (or the distance along the horizontal axis of the map) • While the second 3 figures refer to the northing of the point (or the distance up the vertical axis of the map).

  5. Looking at our number 216 322 Identify the basic Easting and Northing as you would for a four-figure reference . Reference using only the first 2 easting values and the first 2 northing values. Finally, imagine that particular grid square divided into tenths. 216 is the Easting. 21 is the grid line and 6 is the number of tenths toward the next grid line. 322 is the Northing. 32 is the grid line and 2 is the number of tenths toward the next grid line.

  6. This sample will help with your visualization of the square being divided into tenths.

  7. Let’s find the six-figure grid reference for the church on the map below: The church is in grid square 22 31. If we imagine that square divided into 10 parts, the church is 2 tenths further east and 2 tenths further north. So the 6 figure grid reference will be 222 312

  8. Now, try a few on your own: What is the 6 figure grid reference for the church? A 461 325 B 325 460 C 328 460
