The km/h to knots conversion is used to convert speed measurements from kilometers per hour to nautical miles per hour (knots). This is particularly important in maritime and aviation navigation.
The calculator uses the conversion formula:
Where:
Explanation: Since one nautical mile equals 1.852 kilometers, dividing km/h by 1.852 converts it to knots.
Details: Accurate speed conversion is crucial for navigation, weather reporting, and complying with international maritime and aviation regulations that typically use knots as the standard unit.
Tips: Enter speed in kilometers per hour (must be a positive number). The calculator will automatically compute the equivalent speed in knots.
Q1: Why is 1 knot equal to 1.852 km/h?
A: This comes from the definition of a nautical mile (1,852 meters) which is based on the circumference of the Earth.
Q2: Where is knots used as the primary speed unit?
A: Knots are primarily used in maritime and aviation navigation worldwide.
Q3: How accurate is this conversion?
A: The conversion is mathematically exact based on the international definition of the nautical mile.
Q4: Can I convert knots back to km/h?
A: Yes, simply multiply knots by 1.852 to get km/h.
Q5: Why not use km/h for all speed measurements?
A: Nautical miles (and thus knots) are more practical for navigation as they relate directly to latitude measurements.
