Binary to Octal

Welcome! This guide will teach you how to convert binary numbers to octal numbers. Both binary and octal are number systems. Let's start with some basics.

What is a Binary Number?

A binary number uses only two digits: 0 and 1. Computers use binary numbers to process data. Examples include 101 and 1101.

What is an Octal Number?

An octal number uses eight digits: 0, 1, 2, 3, 4, 5, 6, and 7. It's simpler than binary for humans to read. Examples include 7 and 345.

Why Convert Binary to Octal?

Binary numbers can be long and hard to read. Converting them to octal makes them shorter. This helps humans read and understand them better.

Steps to Convert Binary to Octal

Converting binary to octal is easy. Follow these steps:

1. Start with a binary number.
2. Group the binary digits into sets of three. Start from the right.
3. Add extra zeros to the left if needed.
4. Convert each group to its octal equivalent.
5. Combine the octal digits to get the final number.

Example Conversion

Let's convert the binary number 101101 to octal.

Step 1: Group Into Sets Of Three

First, we group the binary digits into sets of three:

Step 2: Add Extra Zeros

We don't need extra zeros here because both groups already have three digits.

Step 3: Convert Each Group

Binary Group	Octal Equivalent
101	5
101	5

So, 101 in binary is 5 in octal.

Step 4: Combine The Octal Digits

We combine the octal digits to get the final number:

So, 101101 in binary is 55 in octal.

Practice Problems
