Wind Loadings

How do I convert a wind speed given in Kph into a loading of newtons per square meter or kilogram per square meter ?

Relivance is to work out the loading on an external window blind (shade).

You would have to assume the wind is coming straight on and the cloth is solid, not perforated, although perforated cloths exist, so would be handy if calculation could take into account how much wind would pass through the cloth.

Seeing as this hasn't been answered I'll toss my hat in the ring. I'm too lazy to do the conversions or look up the formula you seek so I'll post a simple wind speed to pressure calculation in Mph and Pounds per foot

Wind speed squared times .0027 Therefore a 30 mph wind is: 30*30*.0027= 2.43 Pounds per foot of pressure.
