The octal to hex converter translates octal (base-8) numbers into hexadecimal (base-16) notation. Enter an octal value and see the hex result with an intermediate binary expansion shown step by step.
Like hex-to-octal, this conversion uses binary as an intermediate step. First expand each octal digit into three binary bits, then regroup the full binary string into sets of four bits (nibbles) and translate each group to a hex digit.
For example, octal 37 becomes binary 011 111, which regroups as 0001 1111 (after left-padding), giving hex 1F.
Converting octal to hex is helpful when translating between Unix-style octal permissions or legacy octal constants and the hex notation used by modern debuggers, hex editors, and programming environments.
Frequently asked questions
No single-digit mapping exists because 8 and 16 are not powers of each other. The binary intermediate approach is the standard method.
Yes. Convert octal to decimal first, then decimal to hex. The binary-intermediate method is usually quicker for manual work since it avoids division.
