Results Equation
Altitude (meters) Alt= A*12*2.54/100
Temperature Degrees C = ((F-32)*5/9)
Temperature kelvin K = C+273
Barometer  (mbar) = B/(29.92/1013)
Barometer (sea-level) (mb) = 1013*EXP(-B7/7000)
Barometer (sea-level) (in) = mb*(29.92/1013)
Ms (g/kg) = 3.884266*10^((7.5*K)/(237.7+C))
M (g/kg) = Ms*RH/100
Tvc = ((1+1.609*M)/(1+M))*K
Es (saturation pressure mb) = 6.11*10^(7.5*C/(237.7+K))
E (Vapor Ressure mb) = (RH*Es)/100
Tdc = (-430.22+237.7*LN(E))/(-LN(E)+19.08)
Tdf = Tdc*9/5+32
