Hexadecimal conversion transforms numbers between base-16 (hexadecimal) and base-10 (decimal) number systems. Hexadecimal uses digits 0-9 and letters A-F to represent values, where A=10, B=11, C=12, D=13, E=14, and F=15. It's a more compact way to represent binary data, as each hexadecimal digit represents exactly 4 binary digits.
