> That a unit of power has a dozen metric abbreviations and converts to watts at different values depending on what it is measuring (and when) is precisely the point.

How is that point illustrated by an extended digression on the words for the unit in various different languages?

And it worked: it taught you to fish. And you promptly quoted the first screenful of text from the link. Let's call this a win-win and move on, shall we?
