Calculation Formula

Wind Force Level = log10(V^2) where V is wind speed in m/s

Where:
V = Wind Speed (m/s)
log10 = Base-10 logarithm

Wind Force Level Calculator Calculator Usage Guide

Learn how to use the Wind Force Level Calculator and understand the Beaufort scale

How to Use This Calculator

  1. Enter the wind speed in either meters per second (m/s) or kilometers per hour (km/h). You only need to provide one value.
  2. Click the "Calculate" button to determine the wind force level.
  3. The calculator will display the wind force level (from 0 to 12) and a description of what conditions to expect at that force level.
  4. Use the "Reset" button to clear all inputs and start over.

Understanding the Beaufort Scale

The Beaufort scale is a logarithmic scale that relates wind speed to observed conditions at sea or on land. The scale ranges from 0 (calm) to 12 (violent storm). Each level represents specific wind speeds and the effects they have on the environment.

Example Uses

  • Weather enthusiasts wanting to understand current wind conditions
  • Sailors planning outings based on wind strength
  • Emergency preparedness teams assessing potential hazards
  • Students studying meteorology and wind patterns

Formula Explanation

The calculator uses the formula: Force Level = log10(V²) where V is the wind speed in meters per second. This logarithmic relationship means that each whole number increase on the scale represents approximately a doubling of wind speed.
