To convert a measurement in kilometers per second to a measurement in kilometers per hour, multiply the speed by the following conversion ratio: 3,600 kilometers per hour/kilometer per second.

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

kilometers per hour = kilometers per second × 3,600

The speed in kilometers per hour is equal to the speed in 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 hour = (5 km/s × 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.

What Are 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 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/s is expressing a change in length or distance relative to a change in time.

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.

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.

Kilometers per hour can be expressed using the formula:
vkm/h = dkmthr

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