No. Detail to maps. NGR are not accurate only approx

Accurate to 100m is fine for me! Great free tool if you don't need a pro level accuracy - and if you need pro accuracy, you should be prepared to pay.

Its free and ok for my survey work.
its not very good

Many comments stated this is off, one stated by about 100m. If so, then this may be the error: the lat-lng values returned by Google Maps is WSG84-based. But the input to the cited formula should be lat-lng that is Airy1830-based. That conversion might be missing in this tool.

This is such an awesome map to use to locate and find things. I live in New Zealand , and its good to see another country has such detail on my countries features.
Whenever I try to find the grid reference the blue thingymabob keeps going to Ukraine !!!!!!!!
Helpfull but frustrating
not bad at all , postcodes would be a good addition , zoom in on a point and get its postcode

As others have said this is inaccurate!
Do not use it if you need a true grid reference. Use an OS Explorer map instead.
A great shame.

This is inaccurate! See the grab a grid page at http://www.bnhs.co.uk/focuson/grabagridref/html/index.htm
There you can check it against the OS map and its grid lines.
I thought this used to have a search facility. How annoying that it has gone. If there are better tools I will change to them.
Agree with previous comment, for instance 10 Downing Street is shown at TQ 29938 79991 but in reality it is closer to TQ 30040 79918
A search function would be useful, a reverse function would be useful, the northings and eastings are out by at least 100m in places. Useful tool but there are better out there.
Brilliant page. Just what I needed, thanks!
Fantastic...just what I needed. Saved to favourites straight away.

Thanks for this useful tool. It is great for finding coordinates for post codes that are not in OS Code Point Open (when they really should be!).
