The duodecimal system (also known as base 12 or dozenal) is a positional notation numeral system using twelve as its base.
duodecimal (base 12) | base 2 | duodecimal (base 12) | base 2 |
---|---|---|---|
1 | = 1 | b | = 1011 |
2 | = 10 | 10 | = 1100 |
3 | = 11 | 11 | = 1101 |
4 | = 100 | 12 | = 1110 |
5 | = 101 | 13 | = 1111 |
6 | = 110 | 14 | = 10000 |
7 | = 111 | 15 | = 10001 |
8 | = 1000 | 16 | = 10010 |
9 | = 1001 | 17 | = 10011 |
a | = 1010 | 18 | = 10100 |
