Which syllable or syllables are stressed in the word ohmmeter?


I tried to say the word ohmmeter out loud today and realized I am unsure of the correct pronunciation. The double m is confusing to me.

From some research on various ‑meter types, some seem to split the words, whereas others pronounce it in a "run-on" format (for lack of a better description). Like multimeter is usually said as *múlti míter" with stresses on the first and third syllables, but altimeter is usually said with different stress pattern like all tímiter, stressing only the second syllable.

Would it be óhm méter with two stresses or óhm iter with just one, or something else?

    At least one of them says ʹəʋm͵mi:tə (as 2 separate words).

    All the (AmE) dictionaries have pronunciations like /'ow(m) 'mi: tr/. Which is to say " 'owe 'mee tur", stress on the first and second syllable, with an optional long 'm' (whatever that is) or even separation between the first and second syllable. It is written as a single word, but it sounds closer to two words. It is definitely not /'a mi tr/ (even though that is a legitimate possibility.

    One thing to be wary of is allowing the pronunciation to drift towards "ah-meter", which can easily be taken to be "ammeter" (amp-meter), a different kind of meter.

  • @Alex_ander I think you´ll probably find that the gap you´re seeing there is just caused by the secondary stress symbol. (If it was two different words pronunciation-wise there wouldn´t be any secondary stress!) Commented Feb 4, 2019 at 17:42

In my electrical engineering courses in college (Southern United States), I always heard long O, both Ms, primary stress on first syllable, secondary stress on second syllable: OHM-mee-ter. There are two Ms, but the mouth does not open between them. Sort of like Ohmmmmmeeter.

I've listened to both the British and American pronunciations at Collins, and the pronunciation I've heard is somewhere in between those two.

Somewhat like the pronunciation at Merriam-Webster, but with more M on the first syllable.

The closest I've found is the first one at dictionary.com.

I have not heard OHM-ee-ter, which in my mouth requires a glottal stop before the second syllable, or OH-mee-ter, because I'm definitely hearing and saying an M in the first syllable.


I've always heard OHM eeter.
