hexadecimal (base 16) | 120 | 220 | 320 | 420 | 520 | 620 | 720 | 820 | 920 | a20 |
ternary (base 3) | 13 | 23 | 103 | 113 | 123 | 203 | 213 | 223 | 1003 | 1013 |
The ternary numeral system (also called base-3) has three as its base. Analogous to a bit, a ternary digit is a trit (trinary digit). One trit is equivalent to log23 (about 1.58496) bits of information.
