Estimated wind speeds for an F1 tornado on the original Fujita Scale are 73-112 mph. These were found to be inaccurate, though, and were adjusted to 86-110 mph for an EF1 tornado.

An F1 tornado typically has wind speeds ranging from 73 to 112 mph (116 to 180 km/h). These tornadoes are considered weak and can cause moderate damage to structures and vegetation.
An F5 tornado does not form directly from an F1 tornado. Tornado intensity is determined by the Enhanced Fujita Scale based on wind speeds and damage. It is possible for a tornado to rapidly intensify due to various atmospheric conditions, leading to an increase in intensity from an F1 to an F5 tornado.
An F1 tornado is considered weak, with wind speeds ranging from 73 to 112 mph. Damage caused by an F1 tornado can include broken tree branches, shingles blown off roofs, and overturned outdoor furniture. While it is not as destructive as stronger tornadoes, it can still pose a threat to people and property.
An F1 tornado is a rating on the older Fujita scale based on estimated wind speeds, while an EF1 tornado is a rating on the Enhanced Fujita scale which uses more detailed damage indicators to estimate wind speeds. The EF scale provides a more accurate assessment of tornado intensity compared to the older F scale.
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.
A tornado with wind speeds of 75 mph would be rated as an EF0 on the Enhanced Fujita (EF) scale. EF0 tornadoes have wind speeds ranging from 65 to 85 mph and are considered weak tornadoes that cause minor damage.
