Wind Speed Information
Wind Speed Units Explained:
- m/s: Meters per second (SI unit)
- km/h: Kilometers per hour
- mph: Miles per hour
- knots: Nautical miles per hour
- ft/s: Feet per second
- Beaufort: Empirical scale
Common Wind Speed References:
- • Light breeze: 1.5-3.3 m/s (5-12 km/h)
- • Moderate wind: 3.4-5.4 m/s (13-19 km/h)
- • Strong breeze: 10.8-13.8 m/s (39-49 km/h)
- • Tropical storm: 17.5-32.5 m/s (63-117 km/h)
Quick Conversions:
1 m/s = 3.6 km/h
1 m/s ≈ 2.237 mph
1 m/s ≈ 1.944 knots
1 m/s ≈ 3.281 ft/s
Wind Force Calculator
Calculate the force exerted by wind on an object based on wind speed and object area.
Typical values: 1.0 for flat plates, 0.7-1.2 for cars, 0.4-0.6 for spheres

Beaufort Wind Force Scale
| Force | Description | Wind Speed (km/h) | Effects |
|---|---|---|---|
| 0 | Calm | <1 | Smoke rises vertically |
| 1 | Light Air | 1-5 | Smoke drifts slowly |
| 2 | Light Breeze | 6-11 | Leaves rustle, wind felt on face |
| 3 | Gentle Breeze | 12-19 | Leaves and small twigs move |
| 4 | Moderate Breeze | 20-28 | Dust and loose paper raised |
| 5 | Fresh Breeze | 29-38 | Small trees begin to sway |
| 6 | Strong Breeze | 39-49 | Large branches move, umbrellas difficult |
