Lat Long to OSGB Grid

This app takes a given Latitude and Longitude coordinate, in either degree or decimal format, and converts it into an Ordnance Survey grid reference, in either numerical or letter format.

The app also translates backwards, meaning it can convert an OS grid reference to a Latitude and Longitude.

If you have an internet connection, the app will also return your coordinate's what3words equivalent.

If you have your location enabled, the app can get your smartphone's current Latitude and Longitude coordinate and tell you where in the Ordnance Survey grid you are!
