Usage : Type the wind velocity you want to convert into the field, behind which you find the the unit. Click on the corresponding button and read the results in the other fields. Use the "delete" button to delete your calculation.

Example: You want to convert 50 km/h into mi/h. Type "50" into the field in front of the button "km/h". Click on the "km/h" button. Find your result in the field in front of the "mi/h" button (31.069 miles/h).

The Beaufort-unit is given for a range of wind velocities, which are measured at an altitude of 10 m above plain ground in open surroundings. In this converter no input is possible. The scale is divided into 15 values. Often all wind speeds faster than 11 Beaufort are grouped together to 12 Beaufort.
Windchill is the sensible temperature, dependent on the temperature of the air and the wind speed. The calculation only makes sense at low temperatures. You can change the temperature in the corresponding field. However, the calculation is controvers since very often very low temperatures are the result. There is no calculation at wind speed above 25 m/s.
The Pitot-pressure, as measured for example with a Pitot anemometer, is dependent on the density of air. The default value at 1013.25 hPa and 0°C is ρ=1.2923 kg m-3. The value for the density of air might be changed for the calculation.

- All results have been rounded to 5 significant digits.
- Large and small numbers are written exponentially. As example 2.3e5 = 2.3⋅105 = 230000 or 4.5e-5 = 4.5⋅10-5 = 0.000045.
- There is no warranty for the conversion. Cactus2000 is not responsible for damage of any kind caused by wrong results.
- Please send an email if you have suggestions or if you would like to see more conversions to be included.

- A collection of all Cactus2000-converters running offline may be ordered for a price of € 15.-. A test version is available for download for free.
