How to Convert Kilometers Per Second to Kilometers Per Hour

Speedometers are used in vehicles to measure speed

To convert a kilometer per second measurement to a kilometer per hour measurement, multiply 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:

kilometers per hour = kilometers per second × 3,600

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.
5 km/s = (5 × 3,600) = 18,000 km/h

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 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:
vkm/s = dkmtsec

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 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:
vkm/s = dkmthr

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