Hi
Did you ever try Google?
I did and the very first hit looked like what you might want.
 
yes but i did not find a correct answer
 
Don't those calculators do what you want?
 
Hi i need to know how to calculate 300mmwc static pressure. I have to convert this 300mmwc static pressure to CFM.
 
More information needed -- please describe the system.
