## How to Convert Kilometers per Hour to Knots

To convert a measurement in kilometers per hour to a measurement in knots, multiply the speed by the following conversion ratio: 0.539957 knots/kilometer per hour.

Since one kilometer per hour is equal to 0.539957 knots, you can use this simple formula to convert:

The speed in knots is equal to the speed in kilometers per hour multiplied by 0.539957.

**For example,**here's how to convert 5 kilometers per hour to knots using the formula above.

Kilometers per hour and knots are both units used to measure speed. Calculate speed in kilometers per hour or knots using our speed calculator or keep reading to learn more about each unit of measure.

## 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 the expressions of units, the slash, or solidus (/), is used to express a change in one or more units relative to a change in one or more other units.^{[1]} For example, km/h is expressing a change in length or distance relative to a change in time.

Kilometers per hour can be expressed using the formula:

v_{km/h} = d_{km} / t_{hr}

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