Other measures include the [[millioctave]] (mO), which is the 1000th part of an octave, or 1.2 cents; the [[Eptaméride]] or [[Savart]]: 1/301 of an octave; the [[Jot]]: 1/30103 octave; the [[Morion]]: 1/72 octave; the [[Farab]]: 1/144 octave; the [[Flu]]: 1/46032 octave; the [[Purdal]]: 1/9900 octave; the [[Grad]]: 1/12 of a "Pythagorean comma"(or octave?); the [[Mina]]: 1/2460 octave; the [[Mem]]: 1/205 octave (used by [[http://www.h-pi.com/theory/measurement3.html|Hi-pi Instruments]]); the [[Skisma]]: 1/612 octave; the [[Woolhouse]]: 1/730 octave, and the [[Tina]]: a 8539th of an octave (see [[8539edo]]).
