OS Converter: URL Scheme

From Geospike DocWiki

You can load OS Converter, and automatically set one of the 3 text fields using the following scheme:

 
osconverter:?osgrid=TQ 30267 79630
osconverter:?wgs84=51.500603, -0.124640
osconverter:?osgb36=51.500092, -0.123033
 

This will set the field you specified with the given value, and run the conversion.
