163 equal divisions of the octave (abbreviated 163edo or 163ed2), also called 163-tone equal temperament (163tet) or 163 equal temperament (163et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 163 equal parts of about 7.36 ¢ each. Each step represents a frequency ratio of 21/163, or the 163rd root of 2.
163edo tempers out 15625/15552 (kleisma) and [-42 28 -1⟩ in the 5-limit. Using the patent val, it tempers out 1728/1715, 3125/3087, and 413343/409600 in the 7-limit; 2187/2156, 2420/2401, 2835/2816 and 4375/4356 in the 11-limit; 351/350, 640/637, 975/968, 1188/1183, and 1573/1568 in the 13-limit.
