Use this page to convert knots into miles per hour. It is useful when nautical, aviation, or wind speeds need to be compared with US or UK road-speed and weather references.
Knots are based on nautical miles, while miles per hour are based on statute miles.
The mph result is slightly larger than the knot value.
This conversion is common for wind, storms, boats, aircraft, and public weather reporting.
Knots remain more appropriate for navigation and operational marine or aviation use.
Miles per hour can be clearer for general US and UK readers.
This page converts speed, not distance or bearing.
Knots are expected in marine and aviation settings.
Miles per hour is easier for many US and UK readers to understand in weather, vehicle, and general speed contexts.
Converting knots to mph helps present nautical speed values without asking the reader to know nautical miles.
Wind speed may be measured or reported in knots for aviation and marine users.
Public weather summaries in mph-based regions often use miles per hour instead.
The converted value helps both audiences understand the same wind speed.
1 kn should be about 1.15078 mph.
20 kn should be about 23.0156 mph.
If 1 knot becomes 0.868976 mph, the conversion direction has been reversed.
Definition: A knot is a speed of one nautical mile per hour.
History/Origin: Knots are used in maritime navigation, aviation, weather reporting, sailing, and ocean-current measurement.
Current use: knot is used for boats, aircraft, wind forecasts, marine navigation, sailing, currents, and nautical-speed references.
Definition: Miles per hour measures how many miles are traveled in one hour.
History/Origin: Miles per hour is used for road speeds in the United States and the United Kingdom, plus many vehicle and weather references.
Current use: mph is used for road signs, vehicle dashboards, weather reports, aviation references, sports speeds, and travel estimates in mph-based regions.
| Knot [kn] | Mile per hour [mph] |
|---|---|
| 0.01 kn | 0.011508 mph |
| 0.1 kn | 0.115078 mph |
| 1 kn | 1.150779 mph |
| 2 kn | 2.301559 mph |
| 5 kn | 5.753897 mph |

| 20 kn | 23.015589 mph |
| 50 kn | 57.538972 mph |
| 100 kn | 115.077945 mph |
1 kn = 1.150779 mph
1 mph = 0.868976 kn
Formula: value × 1.15077944792
Example: 15 kn = 17.261692 mph
Precision note: Use 1.15077944802 miles per hour per knot. Round according to whether the result is for public display, weather reporting, or technical comparison.
One knot is about 1.15077944802 miles per hour.
Yes. One knot is faster than one mph because one nautical mile is longer than one statute mile.
Use mph for public road-speed or weather communication in mph-based regions. Use knots for marine and aviation operations.
