4 Ways to Calculate Wind Load

May 25, 2020Calculate wind pressure. The simple formula for wind pressure P in imperial units (pounds per square foot) is =, where V is the speed of the wind in miles per hour (mph). To find the pressure in SI units (Newtons per square meter), instead use =, and measure V in meters per second.. This formula is based on the American Society of Civil Engineers code.
