First and foremost, the Saffir-Simpson scale is used to rate hurricanes while the Fujita scale is used to rate tornadoes.
The Saffir-Simpson scale is based on direct wind measurements, with the winds for each category generally being lower than those of the "equivalent" levels on the Fujita Scale (now the Enhanced Fujita scale in the U.S.), for example, a category 5 Hurricane starts at 156 mph while an F5 tornado starts at 261 mph (201 mph for an EF5). Furthermore, the (Enhanced) Fujita scale bases ratings on damage rather than direct wind measurements, with the winds being estimates.
These differences are dues to the fact that tornadoes are much smaller and shorter-lived than hurricanes, making it very difficult or even impossible to get direct wind measurements.
The winds for the (E)F scale categories are higher than those on the Saffir-Simpson scale largely because tornadoes can have much faster winds: tornadoes can have winds over 300 mph, while the very strongest of hurricanes have winds of about 200 mph.
The Fujita scale, used to measure the strength of tornadoes, was developed by Tetsuya Theodore Fujita (1920-1998).Dr. Theodore Fujita first introduced the Fujita Scale in 1971 and was the main inventor, but Allen Pearson, head of the National Severe Storms Forecast Center in Kansas City, Missouri, (now known as the Storm Prediction Center) helped make additions He helped include the path width and path length into the version of the Fujita Scale which was relased in 1973.
The Fujita scale, or Fujita intensity scale, is a scale used to rate tornado intensity based on the damage caused by a tornado. It ranges from F0 (weakest) to F5 (strongest) and is no longer in use, having been replaced by the Enhanced Fujita (EF) scale which takes additional factors into account.
The Fujita (F) scale was originally developed by Dr. Tetsuya Fujita at the University of Chicago. The current scale, the Enhanced Fujita (EF) scale was developed by a large group of engineers and scientists working at Texas Tech University.
EF stands for Enhanced Fujita scale, which is used to classify tornado intensity based on the damage caused. EF2 on the scale indicates a tornado with estimated wind speeds of 111-135 mph that can cause considerable damage.
EF on the tornado scale stands for Enhanced Fujita scale. It is used to classify tornado intensity based on the damage caused by the tornado, ranging from EF0 (weakest) to EF5 (strongest). The EF scale takes into account the strength of the wind and the type of damage observed.

The Fujita Scale was created in 1971 by Dr. Tetsuya "Ted" Fujita.
The Fujita scale is used to classify tornadoes.
The Fujita Scale rates tornadoes based on the damage they cause, ranging from F0 (light damage) to F5 (incredible damage). The Saffir-Simpson Hurricane Wind Scale, on the other hand, categorizes hurricanes from Category 1 (minimal damage) to Category 5 (catastrophic damage) based primarily on sustained wind speeds. Both scales are essential for assessing the potential impact of severe weather events, with Fujita focusing on tornadoes and Saffir-Simpson on hurricanes. Each scale helps inform emergency response and public safety measures.
The most common Fujita scale rating is F0 (EF0 on the Enhanced Fujita scale).

The original scale for rating tornadoes is officially the Fujita-Pearson scale, though the Pearson numbers were rarely used. The scale is normally referred to simply as the Fujita scale. In 2007 the United States stopped using this scale in favor of the Enhanced Fujita scale.
Development of the Fujita Scale began in 1970 and the scale was published in 1971. It was used in the United States until 2007, when it was replaced with the Enhanced Fujita Scale.
