Knots to mph Converter
A knots to mph converter is a tool used to transform knots to miles per hour (mph), for example, if you have a speed of 20 knots, the conversion to miles per hour would be: 20 knots×1.15078≈23.0156 mph.
This conversion is essential in various fields, including aviation, marine navigation, and meteorology. Knots, short for nautical miles per hour, are commonly used in maritime and aeronautical contexts, while miles per hour is a more familiar unit for land-based speed measurements.
- 1 knot = 0.5144 m/s
- 10 knots = 5.144 m/s
- 20 knots = 10.29 m/s
- 50 knots = 25.72 m/s
- 60 knots = 30.87 m/s
- 80 knots = 41.16 m/s
- 400 knots = 205.8 m/s
- 500 knots = 257.2 m/s
How do you convert knots into miles per hour?
To convert a speed given in knots to its equivalent in mph, you need to multiply the number of knots by a conversion factor.
This factor is derived from the relationship between nautical miles and statute miles, which are used in mph calculations.
The conversion process can be broken down into these steps:
- Take the speed in knots.
- Multiply it by the conversion factor of 1.15078.
- The result is the speed in miles per hour.
For example, if you want to convert 20 knots to mph: 20 knots × 1.15078 = 23.0156 mph

Knots to mph Conversion Formula
The formula for converting knots to mph can be expressed as:
Speed in mph = Speed in knots × 1.15078
This formula is based on the definition of a nautical mile, which is slightly longer than a statute mile used in mph calculations.
One nautical mile is equal to 1.15078 statute miles.
When converting from knots (nautical miles per hour) to mph (statute miles per hour), we multiply by this factor to account for the difference in mile definitions.
rough approximation often used is that the speed in mph is about 15% greater than the speed in knots. While not as precise as using the full conversion factor, this can be useful for quick, on-the-spot conversions.
What speed is 10 knots in mph?
Let’s apply the conversion formula to find out what 10 knots equals in miles per hour:
10 knots × 1.15078 = 11.5078 mph
10 knots is equivalent to approximately 11.51 mph.
This conversion demonstrates that a speed of 10 knots is slightly faster than 10 mph, which aligns with our understanding that nautical miles are longer than statute miles.
What speed is 50 knots in mph?
Now, let’s convert a higher speed of 50 knots to mph:
50 knots × 1.15078 = 57.539 mph
50 knots is equivalent to approximately 57.54 mph.
This higher speed conversion showcases how the difference between knots and mph becomes more pronounced at greater velocities, with 50 knots being noticeably faster than 50 mph.
What speed is 25 knots in mph?
For a speed of 25 knots, the conversion to mph would be:
25 knots × 1.15078 = 28.7695 mph
25 knots is equivalent to approximately 28.77 mph.
This conversion falls between our previous examples and further illustrates the consistent relationship between knots and mph across different speeds.
