Measuring Projectile Speed

Well, maybe the thread's title is a bit irrelevant to what I'm about to ask, but I'll give it a try

Does the Projectile Missile Speed value refers to the distance moved per second? For example: Shockwave MPS = 1000. Does that mean it moves 1000 units/second?

I'm asking this question because I need a way to measure the distance between a Caster and a Target and the speed the shockwave is moving. For example, the spell is something like 'Sends a shockwave at a target enemy unit, dealing damage to all in its path and stunning the target for X seconds and dealing X bonus damage.' I'm trying to do this in GUI, so please, guys, don't suggest JASS scripts, because I'm a noob at JASS and I'm a noob at Maths as well!

Yes. It's called Projectile Speed or Missile Speed in the Object Editor.

Art - Missile Speed to be exact.
My guess is range dostance moved in a second. The same range a Unit's attack range counts.
