Klick (unit of length)

This redirect is about the unit of length. For other uses, see Click.

Klick is a common military term meaning kilometer when referring to distance. Its use became popular among US soldiers during the Vietnam War during the 1960s/1970s, although veterans of the war recall its usage as early as the 1950s. The term is of unknown origin. It is likely to be an example of condensed pronunciation or contraction of the term kilometer, although other theories exist.

Click (with same pronunciation but spelled with "c" instead of a "k") is another military term meaning one minute of arc when adjusting the sighting system on a weapon such as a rifle.
