Octal to hex conversion explained
Octal (base 8) and hexadecimal (base 16) are both shorthand for binary, but with different group sizes — 3 bits per octal digit vs 4 bits per hex digit. Converting 377 (octal) gives FF (hex) — both represent 255 in decimal. Hex is the dominant notation in programming (memory addresses, colour codes, byte values), while octal appears in Unix file permissions (chmod 755). For the reverse direction try Hex to Octal, or use the full Base Converter for any radix.
