By using this formula - meters per second x 3.6 = km/h

Divide the distance by the time. That will give you the speed in kilometers/hour. Then divide that by 3.6 to convert to meters/second.
There are 1,000 millimetres in a metre. There are 3,600 seconds in an hour. So to convert you need to multiply by 1,000 and again by 3,600. 100 metres per second = 100,000 millimetres per second. 100,000 millimetres per second = 3,600,000 millimetres per hour.
miles... in kph??? Anyway, the speed of light is 300,000 kilometers/second; you can convert that to whatever unit you want. For example, to convert to kilometers/hour, multiply by 3600.
20 m/s (1 kl/1000 m)(3600 s/1 hr) = 72 kilometers an hour -------------------------------
0.5 (meters / second) = 1.8 kph
