Can't the Vulture do Å ? :)
"Intel Foundry's 18A process node"
I am assuming 18A is 1.8nm aka 18Å.
I don't think there is an el Rego unit for IC fabrication process sizes - I imagine something like what you get when subdividing 1 imperial foot into (12)^6 parts so it would be an embuggerment to go down to next scale viz 1ft/(12)^7 :)
(Troy weight is still around and we could have easily kept 12d/1s if we had moved to the duodecimal number system [and sprouted extra fingers] - 10d/1s, 6d = .6s, 18s/£ 19s/gn but probably replace the £ with a twelve shilling $ :)
