In mathematics and computing, hexadecimal (also base 16, or hex) is a positional numeral system with a radix, or base, of 16. It uses sixteen distinct symbols, most often the symbols 0–9 to represent values zero to nine, and A, B, C, D, E, F (or alternatively a, b, c, d, e, f) to represent values ten to fifteen.
| hexadecimal (base 16) | base 6 | hexadecimal (base 16) | base 6 |
|---|---|---|---|
| 1 | = 1 | b | = 15 |
| 2 | = 2 | c | = 20 |
| 3 | = 3 | d | = 21 |
| 4 | = 4 | e | = 22 |
| 5 | = 5 | f | = 23 |
| 6 | = 10 | 10 | = 24 |
| 7 | = 11 | 11 | = 25 |
| 8 | = 12 | 12 | = 30 |
| 9 | = 13 | 13 | = 31 |
| a | = 14 | 14 | = 32 |
