The term 4K refers to the horizontal resolution of these formats, which are all on the order of 4,000 pixels.
Taken from wiki.

If you compare a 4k tv to 1080 it is actually only twice(3840x2160). But as stated it is the horizontal resolution. They switched it so it sounds like you get a lot more for your money.

1920x1080 = 2,073,600 pixels 3840x2160 = 8,294,400 pixels You get exactly 4 times the number of pixels. A 4k display is exactly 4 1080p displays in a 2x2 array from a size standpoint. The name "4k" is derived from the fact the horizontal resolution is roughly 4000 pixels. 2160p just doesn't have the same ring to it that 1080p\720p does. It has nothing to do with the fact that it has exactly 4 times the number of pixels as a 1080p display does, that's just a coincidence.

You just stated the same thing that I did. If they kept the same format it would be 2160p which still sounds terrible.

I just realized that they switched from naming the vertical to horizontal. Don't know why I never noticed that before.

4kHD is a marketing catch-phrase, not a real format. Also a few that claim 4kHD are cheating a bit and rounding up just to fit with the marketing term. The real names of the formats are on the wiki page for 4kHD:  What we most likely will get on tv and computer displays is UHD because the panel cuts are a frequency of 1080p. Personally I want the DCI 4K 21:9 display @ 4096x1714 but I doubt we'll see that anytime soon if ever.

So you get 4x the pixels but not 4x the resolution

You get 4x the pixels and 4x the resolution. Actual image resolution is really a measure of image quality, not a measure of the length and width of a display. The screen measurement method of conveying resolution is only really used to make it easier to distinguish certain displays from one another, and its easier to say 1920x1080 than recite the number 2073600 whenever you refer to your monitor specs. But resolution ultimately is exactly that: number of pixels.

The term 4K is so misleading I'm expecting it to mean 4x the resolution of 1080p
