None of the tornadoes in the United States recorded before February 1, 2007, were re-categorized during and after the transition to the EF Scale. Essentially, there is no functional difference in how tornadoes are rated. The old ratings and new ratings are smoothly connected with a linear formula.
The EF-scale is more specific in detailing the degrees of damage on different types of structures for a given wind speed. While the F-scale goes from F0 to F12 in theory, the EF-scale is capped at EF5, which is defined as "winds ≥200 miles per hour (320 km/h)". [9]
In 2001, tornado expert Thomas P. Grazulis stated in his book F5–F6 Tornadoes; "In my opinion, if there ever was an F6 tornado caught on video, it was the Pampa, Texas tornado of 1995".

What is the difference between an EF-1 and EF-2 tornado? Tornadoes differ by wind speeds and amount of damage. On the EF Scale, an EF-2 tornado is more severe than an EF-1, with 111 to 135 mph winds.
Here's how tornadoes are rated on the Enhanced Fujita scale and what those ratings mean. What is the Enhanced Fujita scale? What to know about EF tornado categories
The Xenia, Ohio, F5 tornado of April 3, 1974.This was one of two tornadoes to receive a preliminary rating of F6, which was downgraded later to a rating of F5. [1]This is a list of tornadoes which have been officially or unofficially labeled as F5, EF5, IF5, T10-T11, the highest possible ratings on the various tornado intensity scales.
An EF-3 refers to a tornado with estimated winds of 136 to 160 mph (EF stands for the Enhanced Fujita Scale, which became operational for the National Weather Service in 2007).
Houses and stone-walled buildings collapsed. The tornado's maximum width was 850 metres (930 yd) and had a path length of 36 kilometres (22 mi). [8] ESSL: July 17: 1902 Canada: Ontario: Chesterville, Winchester: Several The tornado was 50–60 rods (250–300 m; 820–990 ft) wide and tore dwellings and outbuildings into pieces. [13] [14] [15 ...
