How do you calculate wind speed per hour?
Calculate a miles per hour wind speed in feet per hour, then divide by the number of feet in a knot. For the example wind speed of 100 mph, do as follows: 100 mph x 5,280 feet = 528,000 feet per hour; 528,000 feet per hour/6,080 feet = 86.8 knots.
What is normal wind miles per hour?
In the U.S., daily wind speeds typically average between 6 and 12 miles per hour (10 and 19 kilometers per hour) throughout the course of a year. These averages vary widely by geographic location.
How is average wind speed calculated?
The average wind speed is the simple scalar average of the wind speed observations. A “unit-vector” average is used to calculate the average wind direction. The vectors are then broken down into their u and v components. All u and v components are then averaged separately.
What wind speed is 70 knots?

| 70 | Knots | 129.6 |
| 75 | Knots | 138.9 |
What speed is a strong wind?
| Beaufort number | Description | Speed |
|---|---|---|
| 9 | Strong Gale | 47 to 54 mph |
| 10 | Whole Gale | 55 to 63 mph |
| 11 | Storm Force | 64 to 75 mph |
| 12 | Hurricane Force | over 75 mph |
How fast is 50k wind?

What force is 10 mph wind?
JetStream Max: Beaufort Wind Force Scale
| Beaufort Wind Force | Wind Average | British term |
|---|---|---|
| 0 | 0 | Calm |
| 1 | 2 kt 2 mph 3 km/h | Light air |
| 2 | 5 kt 6 mph 9 km/h | Light breeze |
| 3 | 9 kt 10 mph 16 km/h | Gentle breeze |
Is 10 mph winds strong?
I have always used the guideline of winds between 10 to 20 mph as being “breezy” and winds from 15 to 25 mph or higher to be “windy.” This doesn’t factor in possible gusty winds, just the sustain winds. 6- Strong breeze, 25-31 mph. 8 – Gale, 39-46 mph.
Is it safe to drive in 50 mph winds?
Most drivers are well aware of the hazards posed by inclement weather conditions such as heavy rains, snow, and ice. But what about gusty winds? Winds of even 30 to 45 mph can make driving significantly more dangerous. First, they can actually blow your car off course.
What wind speed is dangerous?
“An Extreme Threat to Life and Property from High Wind.” “Damaging high wind” with sustained speeds greater than 58 mph, or frequent wind gusts greater than 58 mph. Damaging wind conditions are consistent with a high wind warning.
Is 20 knots a strong wind?
For example, when the average wind speed is 25 knots, it is normal to experience gusts of 35 knots and lulls of lighter winds….Wind warnings and gusts.
| Average wind speed (knots) | Gust strength that should be planned for (knots) | Wind Warning thresholds |
|---|---|---|
| 10 | 14 | |
| 15 | 21 | |
| 20 | 28 | |
| 26 – 33 | 36 – 45 | Strong wind warning issued |
How to calculate wind speed for miles per hour?
Wind Speed Conversion Formulas: Conversion formula for Miles per hour to Knots: Wind (kn) = 0.8689762 x Wind (mph) Wind (mph) = 1.1507794 x Wind (kn)
How to convert miles per hour to knots?
Conversion formula for Miles per hour to Knots: Wind (kn) = 0.8689762 x Wind (mph) Wind (mph) = 1.1507794 x Wind (kn) Conversion formula for miles per hour to meters per second:
How does the FT technologies wind speed converter work?
The FT Technologies Wind Speed Converter allows you to convert between different wind speed measurement scales. From SI (meters per second or kilometres per hour) to Imperial (miles per hour or Knots) units or to the Beaufort or Hurricane scale. FT Technologies makes The World’s Toughest Wind Sensors for measuring wind…
What should I subtract from a 3 second wind speed?
In a weather emergency, the gust and sustained wind speeds are broadcast on emergency radio. Subtract 20 if the 3-second gust is greater than 90 mph. Subtract 15 from the result if the 3-second gust is 90 mph or less.
What is the formula for wind speed?
Calculate a miles per hour wind speed in feet per hour, then divide by the number of feet in a knot. For the example wind speed of 100 mph, do as follows: 100 mph x 5,280 feet = 528,000 feet per hour; 528,000 feet per hour/6,080 feet = 86.8 knots.
How to compare Kts to mph in wind speed?
For example, a wind speed of 6.0 KTS is equivalent to a wind speed of 6.0 x 1.15 = 6.9 MPH. Divide the wind speed given in MPH by 1.15 to obtain the equivalent speed in KTS. For example, a wind speed of 10.0 MPH is equivalent to a wind speed of 10.0/1.15 = 8.7 KTS. Compare wind speeds with the same units.
How many miles per hour is wind?
In the U.S., daily wind speeds typically average between 6 and 12 miles per hour (10 and 19 kilometers per hour) throughout the course of a year. These averages vary widely by geographic location.
What is the formula to convert FPS to mph?
FPS to MPH Formula. The formula is simple really. If you want the MPH and have the FPS just multiply the fps x .68181818181.
