"I would think that the accent should properly go as: KEY-low-ME-tur, with the primary accent on the first syllable, beecause:
- “Kilometer” is really a “compound” word, made up of two distinct words (“meter,” a unit of distance…and “kilo,” a prefix meaning “1,000.”) By pronuncing it “kill-OM-e-tur,” you obscure that fact. Heck, “kilo” is used as a word in its own right…or shortened to “K,” indicating 1,000…as in “Y2K.”"
You are correct. The unit and prefix is pronounced separately. Those who insist on mispronouncing kilometre don’t follow through and mispronounce other “metre” words such as centimetre (as cen-tim-e-ter) and millimetre (as mil-lem-e-ter) in the same fashion. Why is that?

"As I go down a top-of-mind list of words ending in “meter” I admit, I’ve gone both ways. I’ve got both -AHmeter words in my vocabulary and blank-o-meter words.
accelerometer barometer diameter electrometer hydrometer kilometer millimeter odometer parameter pedometer perimeter pyrometer speedometer tacheometer tachometer. thermometer…
Just a few from the list and most of these are pronounced AHmeter. Do the brits say these words with the meter separated? Odo MEter? Dia ME ter? Baro MEter? Peri MEter?
If it’s a blanket rule for pronunciation, lots of these words are up for relearning…"
The error in pronouncing kilometre in the US comes from the misspelling of the unit. The unit is correctly spelled metre, not meter in English. The spelling difference distinguishes metre, a unit of measure from meter a device used to measure.
When words are spelled as linderlinder noted, they are pronounced as he noted (om-e-ter). No, the Brits pronounce the meter words as the Americans do. But since they spell kilometre correctly with the -re ending they will know to pronounce kilometre as key-low-me-ter.
Perfect example are the words micrometer vs micrometre. The first is a measuring device and is pronounced my-crom-e-ter, the second is a prefixed unit of the metre and is pronounced my-cro-me-ter (or me-cro-me-ter).
Liter vs litre changes the pronunciation too. Liter is pronounced like lighter and litre is pronounced lee-ter.
The spelling determines the pronunciation. As long Americans have an aversion to spelling metre correctly there will always be a confusion in pronunciation.
