How Do You Spell OHM?

Pronunciation: [ˈə͡ʊəm] (IPA)

The term "ohm" is a unit of electrical resistance named after Georg Simon Ohm, a German physicist of the early nineteenth century. The correct spelling of "ohm" is without an "h" at the end, but many people mistakenly add the extra letter. The word is pronounced as /oʊm/ in IPA phonetic transcription, with a long "o" sound and a silent "h." So next time you need to spell "ohm," remember to drop the "h" and focus on the long "o" sound.
