What is the Ø symbol?

The symbol "ø" (a slashed 'o') has multiple meanings, most commonly representing the empty set (null set) in mathematics, the diameter in engineering/technical drawings, a specific vowel sound in Scandinavian languages (Danish, Norwegian, Faroese), or a way to distinguish the letter 'O' from the number '0' in computing/coding. Its interpretation depends heavily on the context in which it's used.

What does ø symbolize?

Ø or ⌀ is sometimes also used as a symbol for average value, particularly in German-speaking countries. ("Average" in German is Durchschnitt, directly translated as cut-through.)
