Beaufort ScaleKnots to Beaufort

kn to B

Snapshot

1 Knots equals 1 Beaufort.

  • Reference basis: This conversion is threshold-based and maps values to the nearest valid Beaufort level.
  • Example: For 1.625054 Knots, the mapped result equals 1 Beaufort.

Explanation

Input speed is first converted to m/s, then B = (v / 0.836)^(2/3) is applied, rounded to the nearest integer, and clamped to the standard Beaufort range 0-12.

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.
