Methodology·How We Verify

Snapshot

1 Beaufort equals 3.0096 Kilometers per hour.

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.

API, OpenAPI and WebMCP documentation

Explanation

Beaufort force converts to wind speed through the standard relation v = 0.836 * B^(3/2). Output is then mapped from m/s to the selected unit using exact constants.

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.
