Knots Speed Formula:
From: | To: |
Definition: Knots are a unit of speed equal to one nautical mile per hour, used primarily in maritime and aviation contexts.
Purpose: This calculator helps determine speed in knots when you know the distance traveled in nautical miles and the time taken.
The calculator uses the formula:
Where:
Explanation: The distance in nautical miles is divided by the time in hours to calculate speed in knots.
Details: Accurate speed calculation is crucial for navigation, fuel efficiency, and safety in marine and aviation operations.
Tips: Enter the distance in nautical miles and time in hours. All values must be > 0.
Q1: Why use knots instead of mph or km/h?
A: Knots are used because they relate directly to nautical miles, which are based on the Earth's circumference and are more practical for navigation.
Q2: What's the difference between a knot and a nautical mile?
A: A nautical mile is a unit of distance (about 1.15 statute miles), while a knot is a unit of speed (1 nautical mile per hour).
Q3: How do I convert knots to mph?
A: Multiply knots by 1.15078 to get miles per hour.
Q4: Where are knots primarily used?
A: Knots are standard in maritime navigation, aviation, and meteorology (for wind speeds).
Q5: How accurate is this calculation?
A: The calculation is mathematically precise, but actual speed may vary due to currents, winds, and other factors.
