Options
Bulk Processing
Use the text box below to input bulk grid references and find the 'as the crow flies' distances between them. There is a limit of 200 pairs at a time. Add them in the format OS Grid Ref1,OS Grid Ref2 per line. Once processing is complete, the distance is appended as a 3rd column on the CSV list. You can toggle the units (miles/km) using the switch above.
How to Use The Distance Between OS Grid Coordinates
Type in the first and second grid references then click the Show button. The map will then display the location of the two points and also show the routes for:
- As the crow flies - the straight distance between the points
- By land transport - by car and/or boat
You will also see the distance displayed below the map for the distance as the crow flies and also by land transport. You can then type in more paths and click the show button to see more distances.

Hi Mike, it uses Great Circle distances.

That looks great. I%u2019ll try it. Does it take into account the curvature of the earth and the fact that the lines of longitude get closer towards the north. Or is it just Pythagoras? Thanks.

Brilliant! It is rarely necessary to know the straight line distance HOWEVER the secondary tool of providing OS grid for any point clicked is wonderful (and accurate compared to me on the ground gadget. Is it poss to give the output in more digestible SE8526693596 format. Thanks (and thanks even if you can't!)

That's really cool, thank you for doing the work !!!! We are going walking this weekend and will have a go.
Also, with your permission, I'll send it to the teacher who trains the Ten Tors Teams at my daughters school so they can plan training - do you mind if they spread it around?
