## Conversion Definitions

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

### What is kilometers per hour (km/h)?

Kilometers per hour is a unit of Speed or Velocity in the Metric System. It measures the number of kilometers traveled in an hour. The symbol for kilometers per hour is km/h and the International spelling for this unit is kilometres per hour. There are 3.6 km/h in m/s.

### 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 0.2777777778 m/s in km/h.

## 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 km/h to m/s is:

m/s = km/h ÷ 3.6

## Conversion Example

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