Binary to Octal Converter

Why Use This Binary to Octal Tool?

Translating binary code (base-2) into octal (base-8) manually is tedious and error-prone. This Binary to Octal Converter eliminates the guesswork, providing immediate, accurate translations for programming, digital electronics, and file permission configurations (CHMOD). Unlike general calculators, this tool handles padding logic automatically, ensuring your 3-bit groupings are always correct.

The octal system is a critical shorthand for binary in computing, representing three binary bits as one octal digit. Whether you are debugging low-level code or studying computer architecture, our tool delivers the zero-latency results required for professional workflows.

Frequently Asked Questions About Binary to Octal Conversion

How do I convert binary to octal?

Group the binary digits into sets of three, moving from right to left. If the final group on the left has fewer than three digits, add leading zeros to complete it. Finally, replace each 3-bit group with its corresponding octal digit (0-7).

How to convert 10101 binary to octal?

First, pad the number with a leading zero to create groups of three: 010 101. Convert each triplet: 010 becomes 2, and 101 becomes 5. The result is 25.

How do you convert 10010110 binary to octal?

Add a leading zero to align the groups: 010 010 110. Map the values: 010 is 2, 010 is 2, and 110 is 6. The final octal value is 226.

What is the convert binary 101101 to octal?

Split the string into two groups: 101 101. Since 101 equals 5 in octal, the converted result is 55.

What is the octal equivalent of 101010 in binary?

This string is perfectly divisible by three. Group it as 101 010. Converting 101 (5) and 010 (2) yields the octal number 52.
