How do you convert km/h to m/s?

SI unit of distance is a meter according to the International System of Units.

Conversion

We know that

1 km = 1000m

1 h = 3600 s

So 1km /h = 1000/3600 = 5/18 = 0.28 m/sec

So to convert km/h to m/s we multiply the given number by 5/18 or 0.28m/sec

Example

Speed of bicycle = 90 km/hr

To convert the speed into m/sec, we multiply by 5/18

Therefore, speed of bicycle = 90 × 5/18 m/sec = 25 m/sec
