Beaufort ScaleBeaufort to Meters per Second

B to m/s

Snapshot

1 Beaufort equals 0.836 Meters per second. 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 2.364565 Meters per second.
Use the reverse page if you need the opposite direction with the same basis.

Explanation

Formula: speed in m/s = 0.836 x B^(3/2), then convert to Meters per second. 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.

Meters per second (m/s): the SI unit of speed and the canonical wind-speed basis used in this Beaufort model.

This route is useful when translating Beaufort wind-force numbers into practical meters per second 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.

Method & Reference

Method basis: deterministic threshold mapping shown in Snapshot.
Equation reference: v (m/s) = 0.836 * B^(3/2)
Consistency rule: threshold, rounding, and clamping rules stay fixed so outputs remain reproducible.

Questions & answers

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.

How do I switch direction?
