Unilateral Unit System
More actions
The Unilateral Unit System (UUS) is a standardized set of units of measure utilized in T'vaqi. The UUS was officially established shortly following the nation's Second Unification in 244 TT. Initially conceptualized by a group of mathematicians, the UUS was created to reduce confusion regarding exact distances and measurements, and was built to accommodate the existing T'vaqi numeral system. Its establishment was the last action of the Unification Committee before its dissolution. Since its official incorporation into T'vaqi society, the Bureau of Measurement, a government-funded organization ran by several Magisters, has overseen the implementation of UUS units wherever necessary. In 53 PC, conversion formulae for inter-island units of measure were developed by the Bureau of Measurement for trade purposes.
Units
All recognized UUS units of measure and their metric conversions are listed below.
Weight
| Unit | Abbreviation | Relative to previous | Metric conversion (kilograms) | Notes |
|---|---|---|---|---|
| nison |   |
0.15 | Approx. weight of one spoonful of water. | |
| otam |   |
4 nisoni | 0.6 | The most commonly used unit of weight. |
| pa'otam |  |
8 otami | 4.8 | |
| shasa |   |
16 pa'otami | 76.8 | Name translates to "wave". Presumed to be related to the T'vaqi adage "a wave is merely a million droplets". |
| pashasa | |
32 shasi | 2,457.6 |
Distance
| Unit | Abbreviation | Relative to previous | Metric conversion (meters) | Notes |
|---|---|---|---|---|
| qon |  |
0.0035 | Approx. width of a blade of grass. | |
| paqon | |
4 qoni | 0.014 | |
| doqon |  |
8 paqoni | 0.112 | |
| dosha | |
16 doqoni | 1.792 | The most commonly used unit of distance. |
| padosha | |
32 doshi | 57.344 | Often used to measure the heights of buildings. Any structure measuring greater than 2 padoshi is classed as a tower. |
| dodosha | |
64 padoshi | 3,670.016 | A popular track running distance. |
Time
- It should be noted that post-Calming, the Haracalnde has been adopted for most trade and inter-island communication.
Standard T'vaqi units of time are based on subdivisions of the average length of the day. The length of one day is referred to as a pav. Ten shavi make up each day, and ten hoshavi make up each shav. The length of a hoshav can be further broken down into ten sqovi, which are finally broken down into ten hosqovi (or breaths), the shortest common unit of time. The length of a hosqovi is approximately 8.64 seconds.
Standard T'vaqi time has no concept of months or years, and is instead measured in weeks since the Second Unification of T'vaqi. One week passes per ten pavi.
Temperature
Temperature is measured in Common Degrees on a linear scale from 0 to 1. 0 represents the coldest temperature ever measured on the island (equivalent to -26 °C) and 1 represents the hottest (equivalent to 41 °C). Values lower than 0 and greater than 1 are used only for artificial temperatures (e.g. the heat from a fire) that would otherwise not be found in the general climate of T'vaqi.
