About Octal to Hex
This tool reads octal numbers and rewrites them in hexadecimal. Both bases are compact forms of binary, so converting between them is a quick way to switch notations.
Frequently Asked Questions
What digits can I use?
Octal uses only 0 through 7. Separate several numbers with spaces to convert them together.
Is there a limit on the size of the number?
No practical limit. Conversions use big integer math, so even very large numbers convert exactly. Separate multiple numbers with spaces.
