Wind Level, Wind Speed and Wind Pressure Conversion Table
When an object moves, it produce the power.when It moves more faster, the power will be more greater.For example: a car slowly heading toward a wall, maybe it can't knock the wall down, but if you drive at a fast speed, you can knock the wall down. By the same token, although the air is very light, if the speed is very fast, a lot of power can also occur, blowing down the house and pulling up the tree. Based on the calculated result, it is approximately:
At a wind speed of 20 meters per second, there is a pressure of 50 kilograms per square meter.
At a wind speed of 30 meters per second, there is a pressure of 110 kilograms per square meter.
At a wind speed of 40 meters per second, there is a pressure of 190 kilograms per square meter.
At a wind speed of 50 meters per second, there is a pressure of 300 kilograms per square meter.
The wind speed of a typhoon is usually around 40 meters per second, which is about 190 kilograms per square meter. Of course, the relatively simple house will be blown down.The conversion list of wind level, wind speed and wind pressure is shown in Table.

|17||56.1 to 61.2||377 to 449|
|Greater than 17||Greater than 61.2||Greater than 449|
Note: The wind speeds listed in this table are equivalent to the average wind speed in 10 minutes.
