The '''millioctave''' ('''mO''') is a logarithmic [[ | The '''millioctave''' ('''mO''') is a logarithmic [[interval size measure]]. which divides the octave (2/1) into 1000 logarithmically equal parts. Its independence from the "classical"/"standard" [[12edo]] tuning, and its similarity to other metric/[http://en.wikipedia.org/wiki/International_System_of_Units SI] units, have led some microtonalists to prefer it over similar measures such as [[cents]]. However, others note that it naturally favors [[10edo]] and its multiples, just as cents favor 12edo and its multiples. | ||
When comparing the approximations of [[ | When comparing the approximations of [[just interval]]s between different systems, mO values can be used equally well as [[cent]] values. Also the absolute size of [[comma]]s can be given in millioctave steps. | ||
1 millioctave may be defined as a frequency ratio of the 1000th root of 2, or 2^0.001. | 1 millioctave may be defined as a frequency ratio of the 1000th root of 2, or 2^0.001. | ||

1 mO is equal to exactly 1.2 cents. Conversely, 1 cent is equal to exactly 5/6 or ~0.8333 mO. | 1 mO is equal to exactly 1.2 cents. Conversely, 1 cent is equal to exactly 5/6 or ~0.8333 mO. | ||
