> "Other names for the metric horsepower are [...]"

I'm not clear on what point you think you're making. Is it interesting that the same thing might have different names in different languages?

That subsection of the article, by the way, is obviously lying:

> The various units used to indicate this definition (PS, KM, cv, hk, pk, k, ks and ch) all translate to horse power in English.

cv and ch translate to steam horse, which isn't hard to see even if you only speak English. What does "vapor" mean to you?

The opening of the article does suggest some problems, though not problems that wouldn't apply to the word "ounce". But you seem to have pulled an extended quote describing a completely expected state of affairs, while ignoring this:

> There are many different standards and types of horsepower. Two common definitions used today are the imperial horsepower as in "hp" or "bhp" which is about 745.7 watts, and the metric horsepower as in "cv" or "PS" which is approximately 735.5 watts. The electric horsepower "hpE" is exactly 746 watts, while the boiler horsepower is 9809.5 or 9811 watts, depending on the exact year.

I don't get it.

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.

Decibels aren't ridicluous or a unit of measure. Horsepower, however...
