como converter km/h em m/s

How to convert the velocity of one system to another 

For an instance the km/ in m/s, how I already said one kilometer is 1000 meter.

1 hour is the same that 60minute multiply for 60seconds that gives us 3600 seconds.

So in one hour, we have 60 minutes and in one minute we have 60 seconds how many seconds we have in one hour 60x60 that give us 3600 seconds, in one hour we have 3600 seconds.

one kilometer is 1000meters and one hour is 3600, so one kilometer/hours so let's make our formula where is km replace by 1000meters and where is 1 hour replace by 3600seconds, and we gonna have 1000meters/3600seconds. Rute Bezerra de Menezes Gondim
