Slaughtered or not, it's an awkward word to say "properly", and awkward words get changed. I find Kilometer much easier to say the American way "kill-ah-meter"

Slaughtered or not, it's an awkward word to say "properly", and awkward words get changed. I find Kilometer much easier to say the American way "kill-ah-meter", rather than the correct way of "kill-Oh-meter". I suspect people will pronounce these things in a way that isn't painful to the tongue, and memri-stor is that way.
