One of the many advantages of life under the Imperial Apparatus is the easy imposition of consistent standards of infostructure, communication, and law. For fifteen hundred years, the measures of the Eighty Worlds have followed an enviably straightforward scheme.
- There are 100 seconds in each minute, 100 minutes in an hour, and ten hours in a day.
- One second is defined as 1/100,000 of a solar day on Home.
- One meter is defined as 1/300,000,000 of a light-second.
- One gravity is defined as 10 meters per second squared acceleration.
The Emperor has decreed that the speed of light shall remain as nature has provided.
