I will throw my two cents worth in as well. I agree, at times kilowatt can be interpreted as two words --Kilo Watt, and I admit it that is the way I think of it most often. But there are others as well. My father --W0UVX, often calls it Whiskey Zero Ultra Violet X-Ray, that is how he learned it about 50 some odd years ago (his call sign is a former college roommate's call, who later changed it). I have told him, unless he is with people he knows, to use standard calls, because most will hear it as ultraviolet instead of ultra / violet.
One the other hand, using non-standard during field day, also can be confusing. A few years ago someone was using Zanderphar instead of Zulu (or Zed). When it is who knows what time in the middle of the night, or early Sunday morning after hours of operating, sometimes your brain and tongue are not always connecting correctly, and something like Zanderphar is a little hard to get out (for that matter even I am fully awake it is hard). Our Club call is Kilo Zero Golf Quebec, which also can be a tongue twister. Some use Germany, but I like Golf Queen, although...ummm... it might sound a little "funny". But I still thing using a standard -- whatever it be -- should be used, particularly during something like field day. A lot of operations are fast moving, and if the bands are noisy, using fancy phonetics is --at times -- irritating. It all depends on the ones used, and how they are interpreted.
