Top Definition
A numeral system with 3 digits: 0, 1 and 2.

The rightmost digit has the value 1, the digit to the left of it has the value 3 (10=3, 20=6). The digits to the left of that are 3*3 (9), 3*3*3 (27), 3*3*3*3 (81) and so on...

Similar to the binary byte, the ternary system has tryte, six ternary digits. There are 729 possible trytes. (compare with 256 possible bytes!)
Consider the tryte 201202 for example:

2 * 3^5 (243) = 486
0 * 3^4 (81) = 0
1 * 3^3 (27) = 27
2 * 3^2 (9) = 18
0 * 3^1 (3) = 0
2 * 3^0 (1) = 2

486+27+18+2 = 533

So 201202 in ternary means 533 in decimal!
