Loroi standard units are used throughout the Union for interstellar commerce, and to some extent for internal use to aid in standardization.

The Loroi use a base-8 numerical system in many aspects of measurement, which is reflected in their traditional units of time, length, mass, and other quantities. While each planet maintains its own local calendars and customs, an official standard clock and calendar based on Perrein time is used for interstellar commerce, military operations, and official recordkeeping.

Numerical Prefixes

Units can be multiplied with the following base-8 prefixes:

  • nan = 8
  • dinos = 64
  • nestas = 512
  • danzos = 4096

Physical Measurement

One mannal (“pace”) is approximately 0.776 meters.

One malir solon (“radiance beat” or "light-solon") is 327,373 km, the distance light travels in one solon (see Time, below).

One pilo (“stone”), also called bonzir (“mass”), is approximately 160.5 grams (0.354 pounds). It is defined as 827 (or 833 in bijective base-8) times the mass of a helium-4 atom.

One sina (“gravity” or standard gravity) is 9.216 m/sē (approximately 0.94 G). (This is Deinar's surface gravity.)

One nasitosdal sina ("shipboard gravity") is set at 7/8 of standard gravity (0.875 sina, or approximately 0.82 G).

Currency

The basic unit of currency is the moze ("talent"), defined as the yearly output of a laborer. (Standard year of 257 Earth days, approximately $28,000–$33,000 USD in 2026 CE.)

Time

One solon (“beat” or “tick”), 1.092 seconds, roughly defined as one average Loroi heartbeat.

One bima (“moment”) equals one dinosolon or 64 solon (approximately 70 seconds). This unit is infrequently used.

One digel (“cycle”) equals one danzosolon or one dinobima, which is 64 bima, 8 nestasolon, or 4096 solon (approximately 4473 seconds or 1.25 Earth hours).

One tibos ("day" or tozon tibos "standard day") equals 21 digel (approximately 26.09 Earth hours or 1.08 Earth days).

One nanapi (“transit”), 241.92 hours (10.08 Earth days).

One nistil ("year" or tozon nistil "standard year") 256.887 Earth days (0.7033 Earth years).

Calendars and Planet-specific Time

Calendars are primarily a local phenomenon and vary by planet and even by subculture within a planet. Official dates and times use the Standard Year of Unification, counted from the moment of first contact between the Deinar nations on 08:25 March 28, 850 CE.

Starships are usually operated on official (Perrein) time with little regard to local planetary calendars.

Deinar

A Deinar day is 16 digel (approximately 19.88 Earth hours). A Deinar year (tozon) is approximately 350 Earth days or 420 Deinar days.

Deinar has minimal axial tilt and therefore little seasonal change, but solstices and equinoxes are observed as holidays. The young Deinar system experiences frequent comet and meteor activity; recurring dates of periodic comets are often celebrated. The giant comet Semoset returns every 28 Earth years and is the occasion of a major festival of competitive games and feasts lasting the full period of its visibility.

A commonly used sub-segment of the year is the nanapi (“transit”), based on the orbital period of Talas, the larger of Deinar’s two small moons. It is approximately 241.92 hours (10.08 Earth days, 9 Perrein days, or 12 Deinar days). There are about 35 nanapi in a Deinar year. Transits are numbered rather than individually named.

Perrein

The Perrein days and year are the same as the official standard year and day, chosen over Deinar time in part as a political compromise and in part because Perrein has a nearly circular orbit with no moons to affect the length of day. The official clock uses Perrein days that are approximately 26 Earth hours long, with years consisting of 238 Perrein days.

Most local Perrein subdivisions of time are based on localized shifts in the aquifer or other specific biome-related cycles, since the sky is not visible in most places on the planet, and so can vary widely even between locations on Perrein.

Taben

Taben’s day is approximately 13.6 Earth hours and its year is approximately 1.18 Earth years (431 Earth days). Taben has Earth-like axial tilt and therefore experiences seasons, but it has no moons to slow its rotation.
