Convert Eastings and Northings to Lat/Long

[oscarsnan]

How do I convert Eastings and Northings to Latitude and Longitude to enter in my GPS unit please after working the co-ordinates out on a multi cache?

I'm not %100 sure what you need, but a UK geocacher recently created this page, where you can enter co-ords in various different formats and it will convert them to all the other popular formats:

I use the website https://gridreferencefinder.com/ to convert OSGB to postcodes, w3w and so on for work purposes.  It also does WGS84.

 

Personally, I'd tend to work everything in WGS84 Lat/Long as there can be errors brought in when converting (the algorithm has to convert from a spheroid to a localised representation of a flat plane).  It also relies on using the correct datum and projection (I've had work coordinates being 120m out before - not all lat/long systems are the same!)

Rather than converting the coordinates, you should be able to switch your GPS to the OSGB system.  Less chance of error when entering the numbers.
