How to Convert Between Number Bases
Number bases (or radixes) represent values using different sets of digits. Binary (base 2) uses 0 and 1, octal (base 8) uses 0–7, decimal (base 10) uses 0–9, and hexadecimal (base 16) uses 0–9 and A–F.
Why Use Different Number Bases?
Binary is the fundamental language of computers. Hexadecimal is widely used in programming for memory addresses and color codes. Octal was historically used in Unix file permissions. Understanding base conversion is essential for computer science and digital electronics.
