513 equal divisions of the octave (abbreviated 513edo or 513ed2), also called 513-tone equal temperament (513tet) or 513 equal temperament (513et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 513 equal parts of about 2.34 ¢ each. Each step represents a frequency ratio of 21/513, or the 513th root of 2.

513edo divides the steps of 171edo into three. It is consistent to the 11-odd-limit, tempering out 4000/3993, 12005/11979, and 46656/46585 using the patent val. Using the alternative 513e val, 35937/35840, 42592/42525, and 166375/165888 are tempered out in the 11-limit.
