Beaufort ScaleMeters per Second to Beaufort

m/s to B

Snapshot

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

Use the interactive calculator below for custom values and the common-value table for quick checks.

Explanation

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.

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

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 meters per second 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.

Method & Reference

Method basis: deterministic threshold mapping shown in Snapshot.
Equation reference: B = round((v / 0.836)^(2/3)), clamped to 0-12
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?
