Chku

Chku is a fictional term used in speculative fiction and collaborative world-building to describe a versatile unit that can function as both a time measure and a unit of virtual value within an imagined ecosystem. In many uses, chku serves as a short-duration time marker that helps pace scenes or actions, while also serving as a configurable currency or resource within in-universe economies. The dual role allows writers and designers to manage pace and economy with a single concept.

Origin and dissemination: The term emerged in online writing communities and forum-based world-building projects during the 2010s. It spread through fan wikis, writing prompts, and collaborative storytelling, where different authors define chku locally to fit their settings. Because its meaning is not globally fixed, chku is often described as a flexible or context-dependent unit.

Typical definitions and variants: Authors frequently define a chku as a brief time span, commonly on the order of a minute to a few minutes, though exact values differ by universe. As currency, one chku may represent a small unit of value or a charge for a service, with exchange rates adapting to the needs of a given story or game. Some settings separate the time and currency functions, while others blend them for streamlined mechanics.

Usage and reception: Chku is primarily a niche concept in fan fiction and world-building circles. It is valued for its simplicity and adaptability but can be confusing outside its originating communities when overstandardized. See also: world-building, in-universe currencies, time units in fiction.
