    Number Base Conversions for Developers

    Computers represent all data in binary (base 2), but humans typically work in decimal (base 10) or hexadecimal (base 16) when reading memory addresses, color codes, and bitwise values. This converter instantly translates between decimal, binary, octal (base 8), and hexadecimal, making it an essential tool for low-level programming, embedded systems, and digital electronics.

    Hexadecimal is especially prevalent in web development (CSS colors like #FF5733), memory addresses (0x7FFE), and byte representations in debugging. Binary is used in bitmasking, flags, and understanding how computers store integers. Type in any base and all four representations update immediately — no submit button needed.
