B to mph
1 Beaufort = 1.870079 Miles per hour · threshold-based mapping · nearest valid Beaufort level
Direct Answer
1 Beaufort equals 1.870079 Miles per hour
This conversion is threshold-based and maps values to the nearest valid Beaufort level.
For 2 Beaufort, the mapped result equals 5.289381 Miles per hour.

SwitchExplanation
Formula: speed in m/s = 0.836 x B^(3/2), then convert to Miles per hour. Why: Beaufort is an empirical wind-force scale, so the route first maps force number to standard open-water wind speed before any unit change.
Beaufort (B): a standardized empirical wind-force scale from 0 to 12 used to describe observed wind conditions.
Miles per hour (mph): an imperial speed unit commonly used in weather and transport references.
This route is useful when translating Beaufort wind-force numbers into practical miles per hour values for marine, weather, and forecast references.
This conversion is not a simple shared factor in every direction: Beaufort routes use a standardized wind-force mapping, and reverse pages round to the nearest valid force level and clamp results to 0 through 12.
