Knots Formula:
From: | To: |
Knots conversion is the process of converting distance in meters to speed in knots over a specified time period. One knot equals one nautical mile per hour, which is equivalent to 1852 meters per hour.
The calculator uses the knots formula:
Where:
Explanation: This formula converts the distance covered in meters to nautical miles and then calculates the speed in knots (nautical miles per hour).
Details: Knots are the standard unit of speed in maritime and aviation navigation. Accurate knots calculation is essential for navigation, voyage planning, fuel consumption estimation, and safety at sea.
Tips: Enter distance in meters and time in hours. Both values must be positive numbers. The calculator will provide the speed in knots.
Q1: What is a knot exactly?
A: A knot is a unit of speed equal to one nautical mile per hour, where one nautical mile equals 1852 meters.
Q2: Why use knots instead of km/h or mph?
A: Knots are used in navigation because they relate directly to latitude measurements on nautical charts, making navigation calculations simpler.
Q3: How do I convert time from minutes to hours?
A: Divide minutes by 60 to get hours. For example, 30 minutes = 0.5 hours, 15 minutes = 0.25 hours.
Q4: What is a typical cruising speed for ships in knots?
A: Commercial ships typically cruise at 20-25 knots, while large container ships may travel at 24-25 knots. Smaller vessels vary from 5-15 knots.
Q5: Can I use this calculator for air speed calculations?
A: Yes, knots are also used in aviation for airspeed and groundspeed calculations.
