most awesome of you. thank you very much JarkkoL.
for reference, works fine tested with nws windchill calculator
the 2 float values temperature and windspeed are just test numbers, i dont have an anemometer? yet.
void setup(){
Serial.begin(9600);
float T=49;
float V=10;
float Windchill = 35.74 + 0.6215*T - 35.75*pow(V,0.16) + 0.4275*T*pow(V,0.16);
Serial.print(Windchill);
}
void loop(){}
