joulejas

Joulejas are a fictional unit of energy used in certain science-fiction settings to quantify the energy capacities of propulsion, weapons, and shield systems. The jouleja functions as a standardized measure that helps engineers compare power systems across species and factions within its imagined universe.

Definition and name: In-universe, one jouleja is defined as 1,000,000 joules (10^6 J). The unit is abbreviated as Jj (or JJ), and prefixes such as kilojouleja (kJj) and megajouleja (MJj) denote multiples. The term blends the real unit joule with a fictional suffix to signal a distinct scale.

Usage in technology readouts: Joulejas appear on engineering schematics, energy budgets, and combat readouts. A mid-range fusion drive might produce tens to hundreds of Jj per second, while larger starship systems could reach thousands of Jj per second. The system is designed to be compatible with existing metric prefixes for ease of translation.

Origin and prevalence: The jouleja was introduced in the fictional Energetics Charter era by the Energetics Guild to standardize cross-cultural power accounting. It gained wider adoption in interstellar trade and military doctrine, appearing in starship specifications, licensing documents, and technical manuals within the setting.

Reception and notes: Because of its proximity to the real unit joule, the term can cause confusion outside fans of the work. Some sources vary in the stated value or usage context, while others keep to a single definition for internal consistency.
