Process

How Binary to Octal Works

To convert binary to octal, group binary digits in sets of 3 from the right, add leading zeros if needed, then map each group to one octal digit.

01

Start with the binary number

Check that the input contains only 0 and 1, then read the digits from right to left for grouping.

11111111

02

Group bits in threes

Split the binary digits into 3-bit groups from the right. Add leading zeros to the leftmost group when needed.

011 111 111

03

Use the binary to octal table

Convert each 3-bit group to its matching octal digit: 000 through 111 map to 0 through 7.

011 = 3, 111 = 7, 111 = 7

04

Read the octal result

Join the octal digits in order and verify the result with the converter or reference table.

11111111₂ = 377₈

Quick Answers

Popular Binary to Octal Conversions

Direct answers to commonly searched binary to octal questions.

How do you convert binary to octal?

Group binary digits into sets of 3 from right to left. Add leading zeros to complete the first group, then replace each 3-bit group with its octal digit.

11111111₂ = 011 111 111₂ = 377₈

What is the binary to octal table?

The binary to octal table maps each 3-bit binary group to one octal digit: 000 = 0 through 111 = 7.

000→0 · 001→1 · 010→2 · 011→3 · 100→4 · 101→5 · 110→6 · 111→7

What is 101010 in binary to octal?

101010 in binary equals 52 in octal because 101 = 5 and 010 = 2.

101010₂ = 101 010₂ = 52₈
