There is no definite starting point. Officially an EF0 tornado starts at 65 mph, but some have been rated with winds as low as 55 mph. However it is not wind speed alone that qualifies a tornado.
Fire whirls, or whirlwinds spawned by fires, have had winds over 100 mph but don't count as tornadoes because they are not associated with thunderstorms and usually do not connect to cloud base.
Dust devils, which form on hot, sunny days can, on rare occasions, have winds equivalent to an EF0 tornado, but for the same reason as fire whirls are not considered tornadoes.
