Step-by-Step
How to Convert Kilometers per Hour to Knots
Converting km/h to knots is simple when you divide the speed by 1.852.
The Formula
Kilometers per hour and knots are both standard units of speed used in transport, navigation, aviation, weather reporting, and technical measurements. The exact relationship is 1 knot = 1.852 km/h.
To convert knots back to kilometers per hour, multiply by 1.852.
How to Turn km/h into Knots — Step by Step
Write down the speed value
Identify the number of kilometers per hour you want to convert — for example, 72 km/h.
Divide by 1.852
72 km/h ÷ 1.852 = 38.876890 kn. This gives you the equivalent speed in knots.
Label your answer
Always write the unit (kn) after the number so the result is clear and unambiguous.
km/h vs knots
What Is the Difference Between Kilometers per Hour and Knots?
Kilometers per hour and knots are both units of speed. Kilometers per hour are commonly used for road speeds and transport, while knots are widely used in marine navigation, aviation, and meteorology.
The relationship used on this page is: 1 knot = 1.852 km/h. To convert kilometers per hour to knots, divide the number of km/h by 1.852.
For example, 36 km/h = 19.438445 kn, 72 km/h = 38.876890 kn, and 100 km/h = 53.995680 kn.
This conversion is exact and is commonly used in boating, sailing, marine charts, aviation, weather reporting, and technical documentation.
