This statement is not true.
The Fujita or Fujita-Pearson scale is used to measure the intensity of tornadoes. It takes into account the degree of destruction caused by the tornado in structures built by men. The different Fujita levels are shown in the table attached.
On the other hand, the intensity of hurricanes is measured using the Saffir-Simpson scale, which clasifies them from level 1 (the lowest) to level 5 (the highest) depending on the strenght of the winds.
