Enhanced Fujita rating to meters per second
Type a value in EF scale to get it in m/s instantly.
74.21m/s
That's 1.35× as strong as a strong EF2 tornado, while a violent EF4 tornado is 1.1× stronger.
What it means
How strong is that tornado?
EF uses three-second gusts and the old F-scale fastest-quarter-mile winds, so the same rating number means different speeds. Ratings are estimated from damage.
The math
How to convert EF scale to m/s
EF ratings are gust bands: EF0 = 65–85 mph, EF1 = 86–110, EF2 = 111–135, EF3 = 136–165, EF4 = 166–200, EF5 over 200. TORRO: v = 2.365 × (T + 4)^1.5 m/s.
Example: EF4 EF scale = 74.2086 m/s.
