## What is the accuracy of a 6 figure grid in Metres?

100 metres

When obtaining a position from a map scaled at 1:50,000 or 1:25,000; it is appropriate to assume an accuracy of 100 metres, i.e. a 6-figure grid reference. A 6-figure grid reference, therefore, identifies a point anywhere in a square 100 metres by 100 metres.

**How accurate is a 12 figure grid reference?**

These 12 figure co-ordinates locate a point on a map to an accuracy of 1 square metre, in this example a point approximately the centre of the field.

### What is the accuracy of a 4 figure grid reference?

four-figure grid reference, such as ’19 45′, indicates a 1 km by 1 km square on the map; and. six-figure grid reference, such as ‘192 454’, indicates a 100 m by 100 m square on the map.

**How do you make a 8 figure grid?**

In order to obtain an 8 figure grid reference, you need to carry out the exact same procedure to obtain a 6 figure grid reference, dividing your grid square into tenths, but then further sub-divide the 6 figure tenth in which your location lies into further tenths (the 8 figure tenths).

#### How close does a 8 digit grid get you?

within 10 meters

Remember, four-digit grids get you to within 1000 meters, six-digit grids to within 100 meters and an eight-digit grid gets us to within 10 meters. Now, double check your plot and ensure you’ve got it right.

**What is a 6 figure 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 6 figure grid reference?

**What is the accuracy of 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 is the accuracy of an 8 figure grid reference? An 8 figure grid reference will cover an area of 10m by 10m i.e. 100 square meters, the equivalent of less that a quarter of Wimbledonâ€™s centre tennis court.

### How to convert 8 figure grid reference to 6 Figure Reference?

An 8 figure grid reference consists of 2 groups of 4 numbers, Easting and Northings (8 in total). All you need to do to convert an 8 figure reference to a 6 figure reference is to remove the last number from each group of 4 numbers. In other words remove the fourth and eighth digits. This will move you from an accuracy of 10 square meters to one…

**What is the difference between an eight-figure and a six-figure map?**

Eight figure grid references really require a larger scale than this. The numbered grid lines on the E2C 1:25,000 scale map are 1,000 metres apart (1 km). On a 6-figure grid reference the last digit refers to a tenth of the distance between the 1km grid reference lines, so the reference is only accurate to within 100 metres.

#### What is the precision of a grid reference in geography?

Geograph will accept grid references with as little precision as the grid square itself, i.e. 4 figures, or up to 10 figures, which would theoretically locate a feature on the ground with a precision of a 1 metre by 1 metre square.
