What number does h represent in hexadecimal?

In hexadecimal, the letter "h" does not represent a numerical value. Instead, hexadecimal uses the digits 0-9 and the letters A-F (or a-f) to represent values from 0 to 15. Specifically, A represents 10, B represents 11, C represents 12, D represents 13, E represents 14, and F represents 15. Since "h" is not part of the hexadecimal system, it has no numerical equivalent in that context.
