How do you convert a grid reference to latitude and longitude?

Divide the length of the x-axis by 180 and the y-axis by 90. This will give you the equivalent of each latitude (LA) and longitude (LO) angle in inches. Mark the coordinates of a location on the two axes.

How do you convert grid references to Eastings and Northings?

To convert a National Grid Reference to Eastings and Northings:

  1. Remove the two letters at the beginning of the reference: e.g. NS1234 becomes 1234.
  2. Split the reference into it’s East and North components: e.g. 12 East and 34 North.
  3. Work out the numerical reference for the two letters: e.g. NS = 200km East and 600km North.

Can you use OS grid references on Google Maps?

To use Google Maps position the map and, using the zoom tool on the left-hand side of the screen, zoom in to the maximum level to find the place for which you want a Grid Reference. Then either: Click “Grid Reference Tools” and choose “Get Grid Reference from Map”.

How do I convert coordinates?

Community Mapping Experiment: How to Convert Latitude and Longitude to Map Coordinates

  1. Step 1: Multiply (×) the “degrees” by 60.
  2. Step 2: Add (+) the “minutes”
  3. Step 3: If the Latitude (Longitude) degrees are S (W) use a minus sign (“-“) in front.
  4. Step 4: Subtract Reference Location converted to Minutes.

What is the difference between grid reference and coordinates?

Grid references are between the lines which make it look like a maths square that has numbers. The difference between grid references and coordinates is that coordinates are where the lines meet and grid references are in between the lines.

Are grid references and coordinates the same?

Are Northings and Eastings the same as latitude and longitude?

“Easting and northing” are the standard names for the x and y coordinates in any projected (i.e. planar) coordinate system. Additionally, “latitude and longitude” are the standard names for the coordinates in any unprojected (i.e. geographic) coordinate system.

How do you use OS grid references?

Grid references

  1. First, find the four-figure grid reference but leave a space after the first two digits.
  2. Estimate or measure how many tenths across the grid square your symbol lies.
  3. Next, estimate how many tenths up the grid square your symbol lies.
  4. You now have a six figure grid reference.
