Knots to kph Converter
Use our knots to kph converter to convert knots per hour to kilometers per hour (km/h) instantly. Includes the knots to kph conversion formula, why knots are used instead of mph, plus quick examples like 5 knots to mph, 6 knots to mph, and 8 knots to mph.
Knots to kph: How It Works
Knots to kph conversion converts a speed measured in knots (kn) into kilometers per hour (kph or km/h). Since kph is just another way of writing km/h, converting knots to kph means converting knots to kilometers per hour.
A knot is defined as 1 nautical mile per hour. Because a nautical mile is based on Earth’s geometry and maps well to latitude/longitude, knots are commonly used in aviation and marine navigation instead of mph.
If you’re searching “conversion knots to km per hour,” “convert knots to kph,” or “knots per hour to kilometers per hour,” you’re using the same relationship: 1 knot equals 1.852 km/h.
Knots to kph Conversion Formula
To convert knots to kph (km/h), multiply knots by 1.852. To convert kph back to knots, divide by 1.852. For reference, knots can also be converted to mph using a different factor.
This is the standard knots per hour to kilometers per hour conversion.
Use this for the reverse conversion.
Helpful if you also need knots to mph conversion (rounded factor).
So 5 knots is 9.26 km/h (kph).
So 6 knots is 11.112 km/h (kph).
So 8 knots is 14.816 km/h (kph).
So 5 knots is about 5.75 mph.
So 6 knots is about 6.90 mph.
So 8 knots is about 9.21 mph.

Definitions
These quick definitions help clarify what each speed unit means in knots to kph conversion.
- Knot (kn)
- A unit of speed equal to 1 nautical mile per hour.
- kph (km/h)
- Kilometers per hour. “kph” and “km/h” mean the same unit.

Frequently Asked Questions
1 knot equals 1.852 kilometers per hour (km/h). So kph = knots × 1.852.
Yes. A knot already means “nautical miles per hour,” so “knots per hour” is just another way people say it. Converting knots to kph is the same as converting knots to km/h.
Knots are tied to nautical miles and navigation. Because nautical miles relate closely to Earth coordinates and charting, knots are standard in marine and aviation settings.
5 knots is about 5.7539 mph (using mph ≈ knots × 1.15078).
6 knots is about 6.9047 mph (using mph ≈ knots × 1.15078).
8 knots is about 9.2062 mph (using mph ≈ knots × 1.15078).
Multiply by 1.852, then round. A quick estimate is “knots × 2” and subtract about 10% (since 1.852 is slightly less than 2).
Yes. kph is just a shorthand for kilometers per hour (km/h).
