They are pretty much the same because they use the same units.. But velocity... is speed in a particular direction (:

Speed is a scalar quantity that refers to "how fast an object is moving." Speed can be thought of as the rate at which an object covers distance. A fast-moving object has a high speed and covers a relatively large distance in a short amount of time.

Speed has magnitude only while velocity has magnitude and direction.
