The unit of speed that is expressed in terms of kilometers and hours is written as km/h while m/s is the unit of speed which is expressed in terms of meters and seconds.

Converting km/h to m/s means that we are converting the units of a given speed from kilometer per hour to meter per second. This means that, you have to convert the kilometers to meters and then convert the hours to seconds.

### Formula to Convert Km/h to M/s.

The formula to convert kilometers per hour to meters per second is pretty simple.To convert km/h to m/s we convert the kilometers to meters and then the hours to seconds.

We convert km to m by multiplying the kilometers by 1000 and to convert the hours to second we multiply the hours by 3600.

**Km/h to m/s**

**= Km/h x 1000/3600**

On simplifying 1000/3600 further, we get 5/18, which is used as the conversion factor.

**= Km/h x 5/18**

In conclusion, to convert kilometers per hour to meters per second, we multiply the speed in km/h by 5/18.

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

**Example 1:**

Convert 20km/h to m/s.

**= 20 x ^{5}/_{8}**

**= 5.56m/s.**

**Example 2:**

The top speed of Ducati Monster is 225 km/h. Convert this speed to meters per second.

**= 225 x ^{5}/_{8}**

**= 140.625 m/s**

**Example 3:**

If the Porsche 911 Turbo S has a closed-track top speed of 327km/h, while the Lamborghini Huracan will take you to 310km/h. What is the difference in speed of these cars in m/s.

We can either begin by converting both speeds to m/s or begin by finding their difference. In this case, we’ll begin by finding their difference then convert the speed to m/s.

**= 327 – 310**

**= 17 km/h**

Converting km/h to m/s.

**= 17 x ^{5}/_{8}**

**= 10.625 m/s**
