Beaufort Scale Converters
Convert Beaufort wind force numbers and common wind speed units using the standard formula v = 0.836 * B^(3/2). Reverse pages apply the inverse formula, then round to nearest integer and clamp to 0-12.
Explanation
The Beaufort scale is an empirical wind-force scale based on observed effects and standardized speed mapping at 10 m over open water. This hub uses the deterministic WMO-style relation v = 0.836 * B^(3/2) to convert Beaufort to meters per second, then maps to km/h, mph, or knots via exact unit constants. Reverse conversions use B = (v / 0.836)^(2/3), rounded to the nearest integer and clamped to the standard range 0-12.
Beaufort Scale pages are organized by conversion direction so mirror leaves remain aligned and comparable.

Frequently Asked Questions
What is the Beaufort scale?
The Beaufort scale is a standardized empirical wind-force scale (0 to 12) used to describe wind conditions by corresponding speed ranges and observed effects.
What Beaufort numbers are typical in storms?
Strong storms are typically represented by high Beaufort values near the top of the 0-12 range, with severe storm and hurricane-force conditions in the upper levels.
Why does speed to Beaufort require rounding?
The inverse formula produces a continuous value, but Beaufort is conventionally reported as an integer force number, so results are rounded.
Is Beaufort exact or an estimate?
It is a standardized empirical mapping model. This hub uses one deterministic formula for consistency across all mirror pages.
Why clamp to 0-12?
The standard Beaufort force scale is defined from 0 through 12, so reverse results are clamped to remain within that canonical range.
Are unit conversions exact?
Yes. m/s to km/h, mph, and knots use exact fixed constants in this dataset.
What is a knot?
A knot is a speed unit equal to one nautical mile per hour, commonly used in marine and aviation contexts.
