The Fujita scale does not directly rate tornadoes based on wind speed but rather on damage which is used to give a wind speed estimate.
The scale, which was developed in 1971 by Tetsuya Fujita, runs from F0 at the weakest to F5 at the strongest. In recent years scientists have come to believe that the original winds estimates for the Fujita scale were inaccurate, especially for the F4 and F5 levels.
Those wind estimates have been changes on the Enhanced Fujita scale which was developed in 2007. Here are the categories for the Fujita (and Enhanced Fujita) scale with wind estimates and typical damage, but a tornado given a rating on one scale will still get the same rating on the other.
F0 40-72mph (EF0 65-85mph) light damage: tree limbs broken, weak rooted trees uprooted, minor roof damage to most buildings.
F1 72-112 mph (EF1 85-110mph) moderate damage: windows broken, house roofs sustain serious damage, trailers severely damaged.
F2 113-157 mph (EF2 111-135mph) significant damage: roofs torn from strong frame houses, trailers completely destroyed, small vehicles lifted.
F3 158-206 mph (EF3 135-165 mph) severe damage: many or most walls collapse in well-built houses, most trees in a forest uprooted.
F4 207-260 mph (EF4 166-200 mph) devastating damage: strong frame homes completely collapse and reduced to rubble, trees debarked.
F5: 261-318 mph (EF5 over 200 mph) incredible damage: strong frame homes completely swept away, foundations wiped clean.
The speed of the winds in a tornado is called the tornado's wind speed. It is usually measured using the Enhanced Fujita (EF) scale, which categorizes tornadoes based on the estimated wind speed. The wind speed can vary greatly depending on the tornado's intensity, with stronger tornadoes having faster wind speeds.
The wind speed for an EF0 tornado ranges from 65 to 85 mph. These tornadoes are the weakest on the Enhanced Fujita Scale and typically cause minor damage.
Wind speed in a tornado is usually estimated using the damage caused by the tornado's winds and the Fujita scale, which categorizes tornadoes based on their intensity. Meteorologists may also use Doppler radar data to estimate wind speeds within a tornado. Direct measurement of wind speed in a tornado is rare due to the dangerous and unpredictable nature of tornadoes.
The estimated wind speed of an EF0 tornado is 65-85 mph.
The severity of the damage. It is a common misconception that it measure wind speed, but in truth, wind speed estimated based on the damage.
The strength of a tornado is typically determined using the Enhanced Fujita Scale (EF Scale) based on the estimated wind speeds and the damage caused by the tornado. Researchers survey the damage to structures, vegetation, and other objects in the tornado's path to assign it a rating on the scale.

up to 200mph 207 -260 on the regular fujita scale
The estimated wind speed of an EF0 tornado is 65-85 mph.
Yes. The intensity of a tornado is estimated on the Enhanced Fujita scale. On this scale, engineers and meteorologists analyze damage and estimate the wind speed. The highest wind speed estimate is then used to assign a rating, ranging from EF0 for the weakest tornadoes to EF5 for the strongest.
On the original Fujita scale the top wind es for an F1 tornado were set at 112 mph. Winds estimates on the more accurate Enhanced Fujita scale were adjusted for all categories, but the upper bound for anEF1 tornado was shifted only slightly to 110 mph.
The severity of the damage. It is a common misconception that it measure wind speed, but in truth, wind speed estimated based on the damage.
Meteorologists typically infer a tornado's wind speed by analyzing the damage left behind, using the Fujita scale to categorize the intensity of the tornado. They may also use Doppler radar to estimate wind speeds by looking at the rotation of the tornado. Additionally, researchers sometimes deploy mobile instruments like weather balloons or sticknets into tornadoes to directly measure wind speeds.
No wind measurements were taken from the Wichita Falls tornado, so the actual wind speed is not known. The tornado was rated F4 based on the severity of the damage it caused, which suggests peak wind speeds in the range of 207-260 mph. However, recent evidence suggests that the original Fujita scale used to rate this tornado may overestimate the wind speeds needed to inflict F3 and higher damage, so winds may not have been quite so fast.
Tornado strength is assessed on the Enhanced Fujita scale. It is not so much a tool as a set of guidelines. Meteorologists and engineers survey the damage done my a tornado, using it to estimate the wind speed at various points along the path. The highest wind speed is used to assign a rating, ranging from EF0 for the weakest tornadoes to EF5 for the strongest.
