Come Converti Knots
Nautical Speed Conversions Made Simple
Get il ConversionsWeather reports mention 25-knot winds. Ship speeds sono given in knots. Aircraft fly at hundreds di knots. But cos'e un knot in terms di mph o km/h? Comprendere knot conversioni helps you interpret maritime, aviation, e meteorological data.
What Is un Knot?
A knot e un unit di speed equal un one miglio nautico per ora. Il miglio nautico (1.852 km o 1.151 statute miglia) e based on il Earth's geometry—it equivale un one minuto di latitude.
This makes knots ideal per navigation because distance traveled directly relates un position change on charts based on latitude e longitude.
Conversione Table

| 5 | 5.8 | 9.3 | 2.6 |
| 10 | 11.5 | 18.5 | 5.1 |
| 15 | 17.3 | 27.8 | 7.7 |
| 20 | 23.0 | 37.0 | 10.3 |
| 25 | 28.8 | 46.3 | 12.9 |
| 30 | 34.5 | 55.6 | 15.4 |
| 40 | 46.0 | 74.1 | 20.6 |
| 50 | 57.5 | 92.6 | 25.7 |
| 100 | 115.1 | 185.2 | 51.4 |
| 200 | 230.2 | 370.4 | 102.9 |
| 500 | 575.5 | 926.0 | 257.2 |
Conversione Formulas
Knots un Other Unita
- Knots un mph: Multiply da 1.151
- Knots un km/h: Multiply da 1.852
- Knots un m/s: Multiply da 0.514
Other Unita un Knots
- MPH un knots: Divide da 1.151 (o multiply da 0.869)
- KM/H un knots: Divide da 1.852 (o multiply da 0.540)
- M/S un knots: Divide da 0.514 (o multiply da 1.944)
Dove Knots Are Used
Maritime
- Ship e boat speeds worldwide
- Current e tide speeds
- Marine weather forecasts
- Nautical charts e navigation
Aviation
- Aircraft airspeed (indicated e true)
- Wind speed aloft
- International flight planning
- Air traffic control
Meteorology
- Wind speed in weather reports
- Hurricane e tropical storm speeds
- Beaufort wind scale (based on knots)
Wind Speed Riferimento
| Knots | MPH | KM/H | Descrizione |
|---|---|---|---|
| 0-3 | 0-3 | 0-5 | Calm un light air |
| 4-10 | 4-12 | 6-19 | Light breeze |
| 11-21 | 13-24 | 20-39 | Moderate breeze |
| 22-33 | 25-38 | 40-61 | Strong breeze un near gale |
| 34-47 | 39-54 | 62-87 | Gale |
| 48-63 | 55-73 | 88-117 | Storm |
| 64+ | 74+ | 118+ | Hurricane force |
Nota: Hurricane category 1 begins at 64 knots (74 mph, 119 km/h)
Aviation Speed Riferimento
| Aircraft Type | Typical Cruise (knots) | MPH | KM/H |
|---|---|---|---|
| Small prop plane | 100-140 | 115-161 | 185-259 |
| Large turboprop | 250-350 | 288-403 | 463-648 |
| Regional jet | 400-450 | 460-518 | 741-833 |
| Commercial jet | 450-500 | 518-575 | 833-926 |
| Fighter jet | 500-1,200 | 575-1,381 | 926-2,222 |
Conclusione
Knots—miglia nautiche per ora—remain il standard per maritime, aviation, e meteorological speeds worldwide. A convertire un everyday units, multiply knots da 1.151 per mph o 1.852 per km/h. Comprendere these conversioni helps you interpret wind speeds in weather reports, understand boat o aircraft performance, e navigate il world di maritime e aviation terminology.
