Beaufort to Mile per Hour Converter
Speed · unit-converter
Convert Beaufort to Mile per Hour with a fixed input and output unit, step-by-step formula line, and reference tables. All calculations bridge through meters per second with fixed definitions (knot, international mile, Mach 1 = ISA sea level, Beaufort WMO bands at 10 m, vacuum c, plus linear SI and imperial rate units like km/s, fpm, ips, cm/s, and mm/s).
About Beaufort
The Beaufort wind force scale (0–12) describes mean wind at 10 m height. This tool maps forces to midpoint m/s (WMO-style bands) and maps m/s back to a force index.
About Mile per Hour
Miles per hour is used for road speeds primarily in the United States, the United Kingdom, and some other countries.
How to convert beaufort wind force to miles per hour
The Beaufort scale is a discrete wind force (0–12) based on mean wind at 10 m. This tool converts by passing through an equivalent value in meters per second (WMO-style m/s bands; midpoints when starting from a force).
From Beaufort: your input is rounded to the nearest whole force 0–12, then the midpoint m/s for that force is used before converting to mile per hour.
To Beaufort: your speed is converted to m/s, then classified into the matching force 0–12.
Examples
Example #1: Convert 3 beaufort to mile per hour
3 beaufort → 4.400000 m/s (equiv.) → 9.842520 mph. Beaufort: WMO mean wind at 10 m. From Beaufort rounds to force 0–12 then uses midpoint m/s; to Beaufort returns force index.
Result: 9.842519685 mph
Example #2: Convert 7 beaufort to mile per hour
7 beaufort → 15.500000 m/s (equiv.) → 34.672513 mph. Beaufort: WMO mean wind at 10 m. From Beaufort rounds to force 0–12 then uses midpoint m/s; to Beaufort returns force index.
Result: 34.6725125268 mph
Summary
Beaufort conversions use the WMO-style mean wind m/s ranges at 10 m. From Beaufort: your value is rounded to force 0–12, then the midpoint m/s for that force is used. To Beaufort: the m/s equivalent of your input is classified into a force 0–12. Other pairs with Beaufort and Mile per Hour still pass through that m/s bridge.
Relationship context
You are converting between Beaufort and Mile per Hour. Beaufort is a discrete wind scale; conversions use WMO mean-wind m/s bands at 10 m. Linear units (m/s, km/h, mph, knots, etc.) bridge through an equivalent m/s value. Mach and c use fixed m/s definitions for Mach 1 and vacuum c.
