Conversion Formula:
| From: | To: |
The calculator converts speed in knots to miles per hour and calculates distance traveled. 1 knot equals 1.15078 miles per hour, which is essential for maritime and aviation navigation where speed is typically measured in knots but distance may be needed in miles.
The calculator uses two fundamental formulas:
Where:
Explanation: The first equation converts knots to miles per hour, while the second calculates distance using the standard distance = speed × time formula.
Details: These calculations are crucial for navigation, flight planning, maritime operations, and any scenario where you need to estimate travel time or distance covered at a given speed.
Tips: Enter speed in knots and time in hours. The calculator will output speed in miles per hour and distance in miles. All values must be positive numbers.
Q1: Why are nautical miles and knots used?
A: Nautical miles (and knots, which are nautical miles per hour) are used in aviation and maritime navigation because they relate directly to the Earth's latitude/longitude coordinates (1 nautical mile = 1 minute of latitude).
Q2: How accurate is the conversion factor?
A: The conversion factor 1.15078 is exact, as 1 international nautical mile is defined as exactly 1.15078 statute miles.
Q3: Can I calculate time if I know distance and speed?
A: Yes, you can rearrange the formula: Time = Distance / Speed. Just ensure all units are consistent.
Q4: What's the difference between statute miles and nautical miles?
A: A statute mile is 5,280 feet (land mile), while a nautical mile is about 6,076 feet (1,852 meters), based on the Earth's circumference.
Q5: How do I convert the result to kilometers?
A: Multiply miles by 1.60934 to get kilometers. For mph to km/h, use the same conversion factor.
