DSI Units
Currency: The currency within the empire is commonly referred to as “Unit” or “Units” sometimes for “CU” as in Credit Units. Instead of saying large numbers such as Million, Billion and thousand the prefixes are used. When it would cost a Mega Unit or MU it would mean it costs a million credit units.

Galactic Cycle: a mean of measuring time throughout the entire galaxy, it is equal to phi*a year, or about 1,618 years. Like with Units prefixes in front are used to tell for smaller or larger quantities. A milli-cycle is 1 thousandth of a cycle and so forth.
12 milli-cycles is little over 7 days aka a week
17 milli-cycles are almost 10 days.
7 micro-cycles is almost 6 minutes

GVI or Galactic Velocity Index is a mean to measure FTL, Trans-luminal or faster than light speeds, may sometimes be refered to as Warp factor
It is defined so that when you have the velocity factor 1 you travel at the speed of light and each time it increases e times, e is an irrational number that has the approximate value of 2,718…..
The formula would be V=Exp[GVI-1] where Exp means the natural exponetional function.

Distance is measured in parsecs or Ps. A parsec is approximately equal to 3,262 light-years which is the distance a beam of light travel for one year. The closest star to earth other than the sun is 1,306 parsecs away, alpha centaury
