CODE I EDITED


lon =  521490
lat =  192263
height = 0

osgb36point = convertOSGB36toWGS84(lat,lon, height)
oslat = osgb36point[0]
oslon = osgb36point[1]
osh = osgb36point[2]

osUKgridPoint = LatLongToOSGrid(oslat,oslon)
easting  = osUKgridPoint[0].round
northing = osUKgridPoint[1].round


OUTPUT


wgs84 lat:192263, wgs84 lon:521490
Converts to:
osgb36 lat:23.00619802206627, osgb36 lon:-149.99650128215052
Converts to:
easting:-33856949, northing:56599846

(THE LAT AND LONG IS INCORRECT)
