Number Base Converter (Decimal to Binary, Octal, Hex)

Converting a decimal integer to another base repeatedly divides it by that base and records each remainder, starting with the least significant digit — the standard division-remainder algorithm every base conversion uses. This calculator applies it to base 2 (binary), base 8 (octal), and base 16 (hexadecimal, where the digits 10-15 are written A-F).

Bit length is the number of binary digits the value needs (a byte holds 8 bits, so anything from 128-255 needs exactly 8). A value is a power of two exactly when its binary form has a single '1' digit — a useful thing to notice in computing, since powers of two mark clean boundaries like memory sizes and array capacities.
