Speed Conversion Formula:
From: | To: |
Speed conversion from kilometers per hour to knots is essential for maritime and aviation applications where nautical miles per hour (knots) are the standard unit of measurement.
The calculator uses the conversion formula:
Where:
Explanation: This formula converts speed from kilometers per hour to knots by dividing the distance in kilometers by the time in hours and the conversion factor 1.852.
Details: Accurate speed conversion is crucial for navigation, maritime operations, aviation, weather reporting, and international transportation where knots are the standard unit.
Tips: Enter distance in kilometers and time in hours. Both values must be positive numbers. The calculator will provide the speed in knots.
Q1: Why is 1.852 used in the conversion?
A: 1.852 is the exact conversion factor because 1 nautical mile equals 1.852 kilometers, which is based on the Earth's circumference.
Q2: What is the difference between knots and km/h?
A: Knots measure speed in nautical miles per hour, primarily used in maritime and aviation contexts, while km/h measures kilometers per hour, used in land transportation.
Q3: When should I use knots instead of km/h?
A: Use knots for maritime navigation, aviation, meteorology (wind speeds), and any application involving nautical miles.
Q4: How accurate is this conversion?
A: The conversion is mathematically exact since 1 knot = 1.852 km/h by definition.
Q5: Can I convert knots back to km/h?
A: Yes, to convert knots to km/h, multiply the knots value by 1.852.
