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

To convert a kilometer per hour measurement to a kilometer per second measurement, divide the speed by the conversion ratio. One kilometer per second is equal to 3,600 kilometers per hour, so use this simple formula to convert:

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

**For example,**here's how to convert 5,000 kilometers per hour to kilometers per second using the formula above.

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

## Kilometers Per Hour

Kilometers per hour are a measurement of speed expressing the distance travelled 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.

## Kilometers Per Second

Kilometers per second are a measurement of speed expressing the distance travelled 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.

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.
