## How to Convert Knots to Kilometers Per Hour

To convert a knot measurement to a kilometer per hour measurement, multiply the speed by the conversion ratio. One knot is equal to 1.852 kilometers per hour, so use this simple formula to convert:

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.

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

## Knots

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.

## 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:

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

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