Both km/h and m/s are units of speed.

Km/h stands for kilometers per hour while m/s stands for meters per second.

**Formula to convert m/s to km/h.**

To convert meters per second to kilometers per hour we have to convert the meters to kilometers and then the seconds to hours

We convert m to km by dividing the meters by 1000 and to convert the seconds to hours we divide the hours by 3600.

**Km/h – m/s**

**= 3600/1000**

**= 18/5 or 3.6**

In conclusion we say, to convert meters per second to kilometers per second we multiply the speed in m/s by 18/5.

**Speed in km/h = Speed in m/s ** **x 18/5**

**Example:**

Convert 50m/s to km/h.

**= 50 x 18/5**

**= 180km/h**
