Conversion Formula:
From: | To: |
Definition: This calculator converts speed measurements from knots (nautical miles per hour) to miles per hour (statute miles per hour).
Purpose: It helps mariners, aviators, and meteorologists convert between these common speed units used in navigation and weather reporting.
The calculator uses the formula:
Where:
Explanation: 1 knot equals 1.15078 miles per hour because a nautical mile is slightly longer than a statute mile.
Details: Accurate conversion is crucial for navigation, flight planning, and understanding weather reports that may use different units.
Tips: Simply enter the speed in knots. The calculator will instantly provide the equivalent speed in miles per hour.
Q1: Why are knots used instead of mph?
A: Knots are used in aviation and maritime contexts because they relate directly to nautical miles, which are based on Earth's longitude/latitude measurements.
Q2: How accurate is the conversion?
A: The conversion factor (1.15078) is exact, so results are mathematically precise.
Q3: What's the difference between a knot and mph?
A: 1 knot = 1 nautical mile (6,076 feet) per hour, while 1 mph = 1 statute mile (5,280 feet) per hour.
Q4: Is this conversion used in weather reports?
A: Yes, wind speeds are often reported in knots but may need conversion for public understanding in mph.
Q5: Can I convert mph back to knots?
A: Yes, divide mph by 1.15078 to get knots.
