Binary (base 2) uses only 0 and 1. It is the fundamental number system used by all computers and digital systems.

Hexadecimal (base 16) uses digits 0-9 and letters A-F. It provides a compact way to represent binary data — each hex digit equals exactly 4 binary digits.

Can I convert fractional numbers?

This converter handles whole numbers only. Fractional base conversion requires a different algorithm and is not supported.

Why is hex used in programming?

Hexadecimal is compact and maps cleanly to binary (4 bits per digit), making it ideal for representing memory addresses, color codes, and byte values.
