For you all yachts(wo)men, bikers, cyclists -- here is your personal windchill calculator.
t: true temperature [in °Celsius]
v: true velocity wind [in km/h
(kph)]
twc = 33 + ( 0.478 + 0.237*SQRT(v) - 0.0124*v ) * ( t-33 )
Note: The formula gives reasonable results for wind forces from 2 to 9 Beaufort only.
