Pi over 3, or the engineer's comma[idiosyncratic term], is a transcendental ratio of 79.84 cents.

The name "engineer's comma" was proposed by Eliora.

Temperament

π/3 occurs in the Pitave system, which uses a an increase of frequency by a factor of π = 3.14... as an interval of equivalence. Tempering it out means that the pitave is equated to the tritave, 3/1.

Trivia

1 step of 15edo is a very close approximation of this interval.
