because it's shorthand for number and it would represent the number of items in a list/array/map/whatever

  1. It's also called the number sign
  2. Size of a mathematical set S or a group G or whatever is notated as #S or #G.
  3. This gets abstracted out into collections of all sorts and the length of a list is equal to the elements it contains.
