Number Base Converter

Numbers can be represented in different bases (radixes): Binary (base 2) uses only 0s and 1s; Octal (base 8) uses digits 0–7; Decimal (base 10) is the everyday number system; Hexadecimal (base 16) uses 0–9 and A–F. Programmers frequently convert between these — for example, hex is common in memory addresses and color codes, while binary underlies all low-level bitwise operations.
