Wind Speed Converter
Convert between m/s, km/h, mph, knots, and Beaufort scale
Wind Speed Converter
Conversion Formula:
4.17 m/s ÷ 0.447040 = mph
Beaufort Scale: 3 - Gentle breeze
Sea: Large wavelets, crests begin to break. Land: Leaves and small twigs in constant motion, light flags extended
Typical conditions: Flags extended, leaves in constant motion
About Wind Speed Units:
Common Usages:
Meteorology: Knots, mph, km/h, and Beaufort scale
Aviation: Knots are the standard
Marine: Knots and Beaufort scale
Scientific: Meters per second (m/s)
Wind Terminology:
Light winds: Up to 15 knots (28 km/h)
Moderate winds: 15-20 knots (28-37 km/h)
Strong winds: 20-33 knots (37-61 km/h)
Gale: 34-47 knots (62-87 km/h)
Storm: 48-63 knots (88-117 km/h)
Hurricane force: 64+ knots (118+ km/h)
Wind Speed Units Comparison

Wind Speed Visualization
Beaufort 3 - Gentle breeze
This visualization shows how wind at this speed would affect trees, smoke, and clouds. The animation depicts the approximate effects based on the Beaufort scale descriptions.
Wind Safety Tips
- Secure or bring in outdoor furniture during high winds
- Avoid outdoor activities in severe wind warnings
- Be cautious of falling branches and trees
- Allow extra stopping distance when driving in high crosswinds
- Check weather forecasts before marine activities

Common Conversion Formulas
| From | To | Formula |
|---|---|---|
| Meters per second (m/s) | Kilometers per hour (km/h) | km/h = m/s × 3.6 |
| Knots (kn) | Miles per hour (mph) | mph = kn × 1.15078 |
| Beaufort Force (B) | Wind speed (v in m/s) | B ≈ (v/0.836)^(2/3) |
