Cooking with gas:
Haven’t quite worked it out yet. Been a bit distracted again with unneeded but understandably neccessary post councilling and so on but I have the brackets wrong myself so have a consistant but wrong answer for feels like using the previous: https://www.meteoswiss.admin.ch/weather/weather-and-climate-from-a-to-z/wind-chill.html
will look at that anew tomorrow. Nit sure why I could not see it in the tag list. Cheers
this works for apparent temperature in metric units (round(#WCT#+0.33*#WCHN#/100*6.105*exp(17.27*#WCT#/(237.7+#WCT#))-0.7*#WND#-4)) or
(round(#WCT#+0.0201465*#WCHN#*exp(17.27*#WCT#/(237.7+#WCT#))-0.7*#WND#-4))
And this one seems to work for imperial units setting
(round((((#WCT#-32)*5/9)+0.0201465*#WCHN#*exp(17.27*((#WCT#-32)*5/9)/(237.7+((#WCT#-32)*5/9)))-0.7*#WND#*1.6/3.6-4)*9/5)+32)
@petruuccios Thanks - it works perfectly!
My only problem is how you got to the above from the original formula - could you please give me the original formula so that I can try and see how you got from one to the other?
Thanks again.
It comes from the calculator page I suggested earlier, it is also on wikipedia.
it was the water vapour pressure formula and using exp in the tag that fooled me!
thanks again
Do not forget to add formulas for both unit systems and alternate them using #UNITSYS# tag, if you plan on publishing it, or there will be nonsensical results.
Yes indeed - there will be imperial and metric choices. I do intend to publish
