I am trying to bring a calculation that works out the risk of Grass fires.
The original equation is as follows:
where B45 is Curing (how dry the grass is)
B44 is Wind Speed
B43 is Relative Humitity of the air
and B42 is Temperature.
The calculation I got was:
2*Exp(-23.6+(5.01*Ln(Curing)+.001)+(.0281*Temperature)-.266*Sqrt(Relative Humidity+.633*Sqrt(Wind Speed)))
The results are all wrong. What is my mistake?
