given that you have set 'target_unit = METRICWX’, the raw values inside weewx 
are all in the format of the units defined for METRICWX. the unit for speed 
used in METRICWX is indeed ‘m/s’

whenever you display values, weewx converts from whatever the internal format 
is into the units you have requested. if you happen to be displaying in the 
default METRICWX units, it has no conversion to do, but you can request it in 
‘knots’ instead (such as tag $windSpeed.knot) and let weewx sort out conversions

if you want knots as your default displayed unit (in tags, web pages, etc), 
change weewx.conf under [[[Units]]] [[[[Groups]]]] 'group_speed = knot’ (it is 
probably explicitly set to ‘m/s’ at present, or it is that by default if not 
present, you just need to override it)
(note that the configuration line always mentions the unit in singular - ‘knot’ 
not ‘knots’)
