Hexadecimal to Octal Converter
Convert hexadecimal (base-16) numbers to octal (base-8). This converter handles the base conversion accurately for any hex input.
Common Values
How It Works
The easiest method is to convert hex → binary → octal. Expand each hex digit to 4 bits, then regroup into sets of 3 bits from the right for octal. Alternatively, convert hex to decimal first, then decimal to octal.
