How to Convert Knots to Kilometers per Hour

Converting knots to km/h is simple when you multiply the speed by 1.852.

The Formula

Knots and kilometers per hour are both standard units of speed used in transport and navigation. A knot is based on the nautical mile per hour, and the exact relationship is 1 knot = 1.852 km/h.

km/h = knots × 1.852

To convert kilometers per hour back to knots, divide by 1.852.

How to Turn Knots into km/h — Step by Step

1

Write down the speed value

Identify the number of knots you want to convert — for example, 20 knots.

2

Multiply by 1.852

20 knots × 1.852 = 37.04 km/h. This gives you the equivalent speed in kilometers per hour.

3

Label your answer

Always write the unit (km/h) after the number so the result is clear and unambiguous.

What Is the Difference Between Knots and Kilometers per Hour?

Knots and kilometers per hour are both units of speed. Kilometers per hour are commonly used for road speeds and land transport, while knots are widely used in aviation, marine navigation, sailing, and weather reporting.

The relationship used on this page is: 1 knot = 1.852 km/h. To convert knots to kilometers per hour, multiply the number of knots by 1.852.

For example, 10 knots = 18.52 km/h, 20 knots = 37.04 km/h, and 50 knots = 92.6 km/h.

This conversion is exact and is commonly used in ship speed calculations, aircraft speed references, coastal navigation, maritime operations, and technical documents.
