How to Convert Meters per Second to Kilometers per Second

To convert a measurement in meters per second to a measurement in kilometers per second, divide the speed by the following conversion ratio: 1,000 meters per second/kilometer per second.

Since one kilometer per second is equal to 1,000 meters per second, you can use this simple formula to convert:

kilometers per second = meters per second ÷ 1,000

The speed in kilometers per second is equal to the speed in meters per second divided by 1,000.

For example, here's how to convert 500 meters per second to kilometers per second using the formula above.

kilometers per second = (500 m/s ÷ 1,000) = 0.5 km/s

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

What Are Meters per Second?

Meters per second are a measurement of speed expressing the distance traveled in meters in one second.

The meter per second, or metre per second, is the SI derived unit for speed in the metric system. Meters per second can be abbreviated as m/s, and are also sometimes abbreviated as m/sec. For example, 1 meter per second can be written as 1 m/s or 1 m/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, m/s is expressing a change in length or distance relative to a change in time.

Meters per second can be expressed using the formula:
vm/s = dmtsec

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

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.

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.
