The American Civil War is one of the bloodiest military engagements in our nation's history (second only to WWII). A good numerical rundown can be found here. Basically, we lost about 2.6% of our population over 4 years, or 0.00179% per day.
It seems to be generally known that about 100 people/day are dying in "sectarian violence" in Iraq.
So, you want to know if that means civil war? Well, there are about 24 million Iraqis, so they're losing 0.00041% per day. So they're at about 23% of the level of bloodshed we managed in our civil war.
Clearly, Iraq is at peace.
