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

1 Beaufort (B)
SwitchExplanation
Formula: B = round((v / 0.836)^(2/3)), clamped to 0-12 after normalizing speed to m/s. Why: the reverse route maps continuous wind speed into the nearest discrete Beaufort force level.
Miles per hour (mph): an imperial speed unit commonly used in weather and transport references.
Beaufort (B): a standardized empirical wind-force scale from 0 to 12 used to describe observed wind conditions.
This route is useful when classifying measured miles per hour wind speeds into standard Beaufort force levels for charts, marine conditions, and weather reporting.
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.
