B to km/h
Snapshot
1 Beaufort equals 3.0096 Kilometers per hour. Conversion Encyclopedia uses the same fixed conversion basis across the calculator, common values, and reverse page for this page.
- Reference basis: This conversion is threshold-based and maps values to the nearest valid Beaufort level.
- Example: For 2 Beaufort, the mapped result equals 8.512434 Kilometers per hour.
- Use the reverse page if you need the opposite direction with the same basis.

SwitchExplanation
Formula: speed in m/s = 0.836 x B^(3/2), then convert to Kilometers 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.
Kilometers per hour (km/h): a common land-speed unit often used in weather reporting.
This route is useful when translating Beaufort wind-force numbers into practical kilometers 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.

Frequently Asked Questions
What standard is used for Beaufort conversion?
This page uses v = 0.836 * B^(3/2) at 10 m over open water, with exact unit factors for m/s, km/h, mph, and knots.
How is speed to Beaufort handled?
Reverse pages compute B = (v / 0.836)^(2/3), then round to the nearest integer and clamp the result to 0 through 12.
