## How to Convert Kilometers Per Second to Kilometers Per Hour

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

Since one kilometer per second is equal to 3,600 kilometers per hour, you can use this simple formula to convert:

The speed in kilometers per hour is equal to the kilometers per second multiplied by 3,600.

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

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

## Kilometers Per Second

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

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

In formal expressions, the slash, or solidus (/), is used to separate units used to indicate division in an expression.^{[1]}

Kilometers per second can be expressed using the formula:

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

The velocity in kilometers per second is equal to the distance in kilometers divided by time in seconds.

## 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.

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.
