Easily convert between British National Grid References (OS Grid Refs) and Latitude, Longitude coordinates (both OSGB36 and WGS84 are supplied).

Then, easily view the converted coordinate in the Maps app, or send it to GPS Log (our app for recording your travels). Or copy to the clipboard using the standard iPhone functions.

Fuzzy parsing logic allows you to input coordinates in a variety of ways, like "TQ 30267 76930", and "TQ302769".
