The Diameter symbol (⌀) is commonly used in engineering, mathematics, and science to denote the diameter of a circle or a circular object.

It’s a straightforward yet essential symbol in technical fields, particularly in mechanical design and drafting.

*It is also called the ‘O with stroke’ symbol or ‘Slashed O’ symbol, as it looks as if there is an O that is slashed by a line*.
