To convert a knot measurement to a kilometer per hour measurement, multiply the speed by the conversion ratio.

Since one knot is equal to 1.852 kilometers per hour, you can use this simple formula to convert:

kilometers per hour = knots × 1.852

The speed in kilometers per hour is equal to the knots multiplied by 1.852.

For example, here's how to convert 5 knots to kilometers per hour using the formula above.
5 kn = (5 × 1.852) = 9.26 km/h

Knots and kilometers per hour are both units used to measure speed. Keep reading to learn more about each unit of measure.

What is a Knot?

One knot is equal to a speed of one nautical mile per hour,[1] or one minute of latitude per hour.

Knots can be abbreviated as kn, and are also sometimes abbreviated as kt. For example, 1 knot can be written as 1 kn or 1 kt.

What Are Kilometers per Hour?

Kilometers per hour are a measurement of speed expressing the distance traveled in kilometers in one hour.

The kilometer per hour, or kilometre per hour, is an SI unit of speed in the metric system. Kilometers per hour can be abbreviated as km/h, and are also sometimes abbreviated as kph. For example, 1 kilometer per hour can be written as 1 km/h or 1 kph.

In formal expressions, the slash, or solidus (/), is used to separate units used to indicate division in an expression.[2]

Kilometers per hour can be expressed using the formula:
vkm/h = dkmthr

The velocity in kilometers per hour is equal to the distance in kilometers divided by time in hours.
