QFE - what is it and what use is it to me in WD?

AS i understand it, QFE is air pressure at above sea-level?

So if i set me altitude in WD as 0 and enable QFE, will i be able to view sea-level pressure and station prerssure on the detailed NOAA reports?

Thanks for any help

its field pressure, usefull only for people at high altitude and cold climate
you do not need to use it
