grammar - Why do we say " 'a' unit instead of 'an' unit

As title suggest, wondering what the literary rule is for "A unit." Unit being a noun would need an article. I have generally understood that the a/an decision is if the vowel sound if the lead sound ex: "an hourglass, but a glass".



it seems to me very clearly the "U" sound is the lead here, but for word that start with the 'you-enn' sound (unit, uniform, unabomber), we use "a".
