Weights and measures in Themiclesia
Weights and measures in Themiclesia are a system of standard units quantifying the metrics of length, mass, and volume; other units can be derived from any one of these systems. Themiclesian law accepts the Metric system in its entirety, though a domestic system with a historical origin common with that in Menghe is also in use. The latter system is prevalent over the Metric system in certain contexts, such as the measure of cloth, alcohol, precious metals, cooking ingredients, grains, and medicinal herbs. Most definitions are found within Chapter XXX of the Administrative Code.
Length
The Themiclesian system for calculating length is for the most part decimal. The basic unit is a ts'jak or Themiclesian foot, measuring 24.5 mm; this length is derived from the wavelength of a 1,400 Hz sine wave travelling through air at sea level atmospheric pressure.
