Binary is a base-2 number system that uses only two digits: 0 and 1. It is the fundamental language of computers, where 0 represents "off" and 1 represents "on".

Hexadecimal (or hex) is a base-16 system using digits 0-9 and letters A-F. It is often used in computing to represent binary data in a more human-readable format.

Why do we use different number systems?

Different systems are useful for different tasks. Binary is how hardware works, hex is good for representing colors or memory addresses, and decimal is what humans use daily.

Can I convert negative numbers?

This tool is primarily for positive integers. Negative numbers in binary are typically represented using methods like Two's Complement, which requires a fixed bit width (like 8-bit or 16-bit).
