What Is the Wind Speed Converter?

A wind speed converter translates wind velocities between marine, aviation, civil, and scientific units with Beaufort scale ratings.

How Does the Wind Speed Converter Work?

Applies international speed conversion ratios and maps results to empirical visual Beaufort scale effects.

Wind Speed Converter Formula & Variables

The core mathematical equation utilized by this calculator is expressed as:

1 Knot = 1.15078 MPH = 1.852 km/h = 0.51444 m/s

Normalizes input to meters per second and classifies wind intensity against the 0–12 Beaufort Scale scale.

How to Use the Wind Speed Converter

  1. Enter the wind speed value and select its unit (knots, mph, km/h, m/s).
