But you would think they would also say "one second" instead of "one half," but they don't. They're still saying "one half." "One second" might be confused with "one sixtieth" because there are sixty seconds in a minute, and sixty seconds in a degree.

I'd say 1/81 is "one eighty-first."

There are 60 seconds in a minute of angle, and 60 minutes in a degree.
