How can we convert m/s into km/h

To convert m/s in km/h , simply multiply speed/velocity in m/s by 18/5.The answer we get is speed/velocity in km/h.

Since to turn m into km, we have to divide distance in meter by 1000 (as 1000 meter= 1 kilometer).And to convert seconds in hour we have to devide time in seconds by 3600 s. Since one hour is equal to 3600 seconds.
