Seamless Speed Conversion: Knots to MPH Explained
What is a Knots to MPH Converter?
A Knots to MPH Converter is a tool that translates speed from knots to miles per hour. This is a common conversion for those interested in aviation or maritime activities, as a knot—one nautical mile per hour—is the standard unit in these fields. Converting to miles per hour (mph), the familiar unit for land speed in the US and UK, helps to better contextualize these speeds.
How to Use the Knots to MPH Converter
Our tool offers instant, two-way conversions.
- Enter a value: Type your speed into either the "Knots" or "Miles per hour (mph)" field.
- Get the result: The equivalent speed will appear in the other field automatically.
The Conversion Formula
A nautical mile is longer than a statute mile, which is reflected in the conversion factor.
$$ 1 \text{ knot} \approx 1.15078 \text{ mph} $$
The formulas are:
$$ \text{mph} = \text{knots} \times 1.15078 $$
$$ \text{knots} = \frac{\text{mph}}{1.15078} $$
Practical Example: Boating Speed
A weather report for a coastal area warns of winds at 25 knots. A boater wants to understand how this compares to land-based wind speeds they are familiar with.
- Known Value: 25 knots
- Calculation: mph = 25 × 1.15078 ≈ 28.77 mph
- Using the calculator: Entering "25" into the knots field will instantly show the result of ~28.77 mph.
This helps the boater understand the wind's strength. For other conversions, see our main Speed Converter or the Knots to km/h Converter.
For more information, the National Ocean Service provides great explanations of these units. For aviation data, the FAA website is an authoritative source.
