Metric

A Metric is a unit of measurement.

• Science is largely based on accurate systems of experimentation and measurement.
• 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 sophonts 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.

Scientific Metrics

Scientific metrics measure the physical environment and electromagnetic phenomena among other measurable characteristics.

History & Background (Dossier)

The Rule of Man succeeded in instituting many Terran metrics that replaced many of the earlier Vilani metrics. Some of the Vilani metrics survive in Vilani Space and as elements of folk sayings.

Socioeconomic Metrics

In contrast to mostly tangible scientific metrics, socioeconomic metrics measure social and economic relationships.
