Standard units
From 1ste Gimnechiske Wiki
To avoid problems, information about this univers is based on standard units. All these units might be prefixed standard to destinguish them from other types of units. Local variations can be identified on the pages about various planets. The use of standard units can be compared to the use of ISO standards on our own world. For fantasy worlds, check out historical units. These definitions is to be as clear as possible to avoid misunderstandings and arguments during an RPG session. Before using ISO units, or even inventing your own units, read Measuring Units in Fantasy.

Time
Year
The Length of an earth year, or 365 earth days. One earth day is of course 24 standard hours.
Hour
A 24th of an earth day. Standard hours are used to measure universal time. Some places "planet hour" might be stated. This is a 24th of a planet revolution. Hours are devided in minutes (a 60th of an hour) and secunds (60th of a minute). For finer scales, fractions of secunds are used.
Length
Meter
A meter is defined as a 10.000.000th of the distance between Equator and the poles on earth.
AU
Astronomic Units. The definition is seriously advanced.
Jumps
This is a more practical description for travel time or the limitations of a certain craft. The Interstellar routes between the majore systems are noted in number of Jumps, which checked against the vessels characteristics can give the travel time. Worm holes are also marked with number of jumps, which in the same way give the time to travel through the worm hole. Actuall travel distance is often larger when travelling through worm holes, as they in some way are folding space, and forming some sort of inter-dimentional short-cut between two locations. See Worm Hole Travel for more details about worm holes.
Area
Meter Square
Is the area of a square where the sides are 1 meter each, denoted meter square or m².
Volume
Liter
A liter is the volume of a cube where the each of the sides are 10th of a meter (1 dm), and can also be denoted as 1 dm³. This is a much used unit to measure usable quantities of liquids such as potable water.
Meter Cube
Denoted m³, is the volume of a cube, where each of the sides are 1 meter.
Mass/Weight
Kilogram
Also known only as Kilo, denoted kg. One kilo is the weight of 1 liter of pure water.
Tonn
Usually used for larger masses. One tonn is for instance the weight of a m³ of water, or 1000 liters. One tonn is the same as 1000kg.
Temperature
Centigrades
Denoted °C, are based upon Celsius scale for temperature. 0°C is the temperature pure water freezes in normal athmospheric preasure, and 100°C is the temperature where pure water evaporates in the same preasure.
Preasure
Athmospheric Preasure
Athmospheric Preasure is the preasure on sea level at earth, and denoted one athmosphere. You will also add one athmosphere for each 10 meter of water you are submerged into. Other planets might have a higher or lower athmospheric preasuer, and even on earth the athmospheric preasure changes with the weather conditions. The average preasure on earth, which is the base for this scale is 1013 hPa.
Gravity
Gravity is based upon Newtons law, and is compared with acceleration. It is denoted in N/s². Normal earth gravity is 9,81 N/s².
Also known as G-Force, where 1 G is equal to earth gravity. Vehicle accelerating and decelerating are often mentioned in number of G's, as well as the force on a pilot or passenger during steep curves also can be noted in G's. The maximum G's a certain race can handle should be noted from a formula, but I havn't seen any examples yet, and have no idea of where to start creating such formula.
