The correct conversions are:
km/h 3.6 = m/s and m/s 3.6 = km/h
m/s 3.6 = km/h and km/h 3.6 = m/s
m/s 3.6 = km/h and km/h 3.6 = m/s
m/s 3.6 = km/h and km/h 3.6 = m/s

The difference between speed and velocity is that
Speed tells how fast the object is moving along the ground covered, while velocity tells how fast the object has been displaced in a particular direction.
Speed and velocity are always the same.
Speed is with respect to time while velocity is with respect to speed.
Velocity tells how fast the object is moving along the ground covered while speed tells how fast the object has been displaced in a particular direction.
