## Conversion Definitions

The following is a list of definitions relating to conversions between meters per second and kilometers per second.

### What is meters per second (m/s)?

Meters per second is a unit of Speed or Velocity in the Metric System. It measures the number of meters traveled in a second. The symbol for meters per second is m/s and the International spelling for this unit is metres per second. There are 1,000 m/s in km/s.

### What is kilometers per second (km/s)?

Kilometers per second is a unit of Speed or Velocity in the Metric System. It measures the number of kilometers traveled in a second. The symbol for kilometers per second is km/s and the International spelling for this unit is kilometres per second. There are 0.001 km/s in m/s.

## Conversion Formula

Let's take a closer look at the conversion formula so that you can do these conversions yourself with a calculator or with an old-fashioned pencil and paper.

The formula to convert from m/s to km/s is:

km/s = m/s ÷ 1,000

## Conversion Example

Next, let's look at an example showing the work and calculations that are involved in converting from meters per second to kilometers per second (m/s to km/s).

### Meters per second to Kilometers per second Conversion Example

Task: Convert 450 meters per second to kilometers per second (show work)Formula:m/s ÷ 1,000 = km/sCalculations:450 m/s ÷ 1,000 = 0.45 km/sResult:450 m/s is equal to 0.45 km/s
