The Fujita scale (F-Scale; / f u ˈ dʒ iː t ə /), or Fujita–Pearson scale (FPP scale), is a scale for rating tornado intensity, based primarily on the damage tornadoes inflict on human-built structures and vegetation.
Tornadoes are rated by their intensity and the damaged they cause to vegetation and human created structures. The Fujita scale (F-Scale), also known as the Fujita-Pearson scale, is a tornado scale that was introduced in 1971 by Tetsuya Fujita.
The Enhanced Fujita scale (abbreviated as EF-Scale) rates tornado intensity based on the severity of the damage they cause. It is used in some countries, including the United States and France. [1] The EF scale is also unofficially used in other countries, including China. [2]

[1] It is used by the European Severe Storms Laboratory (ESSL) and various other organizations including Deutscher Wetterdienst (DWD) and State Meteorological Agency (AEMET).
The EF Scale primarily classifies tornadoes based on the damage left behind. By surveying the damage, scientists assign a wind speed that is likely to have caused that damage. There are 28 categories that range from flagpoles and power lines all the way up to schools and high-rise buildings.
