About Octal to Binary
This tool rewrites octal numbers in binary. Each octal digit expands to three binary bits, and the math stays exact for large values.
Frequently Asked Questions
What digits can I use?
Octal uses only the digits 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.
