-A [[Metric]] is a unit of measurement.
-* [[Science]] is largely based on accurate systems of experimentation and measurement.
-* [[Ship Sensor Suite|Sensors]] and scientific instruments rely on accurate metrics to quantify their readings and data.
-== Description ([[Specifications]]) ==
-''Metrics'' are the abstract, intangible idea-tools by which [[sophont]]s measure their [[environment]] and what they interact with. Almost every [[sophont]] species and [[world-state]] develops an indigenous system of measurement and then converts to the system used by the interstellar community when they join it. This leaves a field of many different systems of measurement coexisting, in which one system is used as the primary system of study and intellectual exchange. {{Unpublished cite|author= [[Maksim-Smelchak]] }}
-=== Scientific Metrics ===
-Scientific metrics are employed to measure and quantify properties of the physical [[environment]] derived thru scientific observation and experimentation. Various physical properties will be assigned relative values according to associated standard metric scales by which they are quantified. Scale parameters can be modified for ease of manipulation and recording by the addition of a [[Imperial Standard Metric Prefix|standardized prefix multiplier]] to the metric unit.

-== History & Background ([[Dossier]]) ==
-Modern Imperial Metrics are largely derived from an amalgamation of the ruling predecessor cultures that imposed their own systems during earlier Imperia. By far the most influential of these were the old Solomani systems known as the ''"'''S'''ystème '''I'''nternational d'Unités"'' or ''"'''SI'''-Units"'' (or today as the '''''S'''tandard '''I'''mperial ('''SI''') System of Units and Metrics'') and it's associated decimalized unit measurement system known simply as the ''"Metric System"'' (the basis of the ''[[Imperial Standard Metric Prefix]]''). In many cases, modern Imperial Metrics have been generalized by unfettering them from highly specified dependence upon conditíns in an originating star system by standardisation thru rounding and decimalization - a process known as metrication.
-=== Old Vilani Metrics ===
-Old Vilani metrics (or corrupted versions descended from them) are still sometimes found in limited use locally where Vilani cultural heritage remains strong.
-==== Vilani Distances ====
-The Vilani measured distances in
-* [[Dictionary:Shiig|Shiig]] (~ "Inch") ≈ 34 mm
-* [[Dictionary:Amiran|Amiran]] = 5 Shiig (≈ 170 mm)
-* [[Dictionary:Edapu|Edapu]] = 5 Amiran (≈ 850 mm)
-* [[Dictionary:Khaniimi|Khaniimi]] = 5 edapu, (≈ 4.25 meters)
-* [[Dictionary:Daakuu|Daakuu]] = 500 Khaniimi, (≈ 2.125 km.)
-* [[Dictionary:Deshi|Deshi]] (''"Vilani Parsec"'') ≈ 2.17 ly
-=== The Rule of Man ===
-The [[Rule of Man]] succeeded in instituting many [[Terra (world)|Terran]] metrics that replaced many of the earlier [[Vilani Imperium|Vilani]] metrics. Some of the [[Vilani Imperium|Vilani]] metrics survive in [[Vilani Space]] and as elements of folk sayings.{{Unpublished cite|author= [[Maksim-Smelchak]] }}
-=== Socioeconomic Metrics ===
-In contrast to mostly tangible scientific metrics, socioeconomic metrics measure social and economic relationships.
-==== Economic Metrics ====
-* [[Avery-Quesnay Economic Scale]] ([[AQEC]])
-* [[Bilateral Trade Number]] ([[BTN]])
-* [[Economic Extension]] ([[Ex]])
-* [[Gross Polity Product ]] ([[GPP]])
-* [[Gross Sector Product]] ([[GSP]])
