The duodecimal system (also known as base 12 or dozenal) is a positional notation numeral system using twelve as its base.
| duodecimal (base 12) | ternary (base 3) | duodecimal (base 12) | ternary (base 3) |
|---|---|---|---|
| 1 | = 1 | b | = 102 |
| 2 | = 2 | 10 | = 110 |
| 3 | = 10 | 11 | = 111 |
| 4 | = 11 | 12 | = 112 |
| 5 | = 12 | 13 | = 120 |
| 6 | = 20 | 14 | = 121 |
| 7 | = 21 | 15 | = 122 |
| 8 | = 22 | 16 | = 200 |
| 9 | = 100 | 17 | = 201 |
| a | = 101 | 18 | = 202 |
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.
| ternary (base 3) | duodecimal (base 12) | ternary (base 3) | duodecimal (base 12) |

| 1 | ≈ 1 | 102 | ≈ b |
| 2 | ≈ 2 | 110 | ≈ 10 |
| 10 | ≈ 3 | 111 | ≈ 11 |
| 11 | ≈ 4 | 112 | ≈ 12 |
| 12 | ≈ 5 | 120 | ≈ 13 |
| 20 | ≈ 6 | 121 | ≈ 14 |
