Octal to Binary Converter Online

Octal to Binary Converter is a simple tool that converts numbers from the octal system (base 8) to the binary system (base 2). The octal system uses digits between 0 and 7 and is often used in computing because it provides a shortcut for writing binary data. The binary system, which works only with 0 and 1, is the basic language of computers and is used to store and process all data.

Converting from octal to binary is easy because each octal digit has a direct three-bit binary match. This makes the process fast and useful in programming, digital circuits, and number system tasks.

With this free online converter, you simply enter your octal values, and they are instantly converted to binary values. No ads or extra steps – just a clean and simple base-8 to base-2 conversion tool. It is designed for developers and learners who want fast and accurate results.

What is the Octal Number System?

The octal number system, also called oct, uses base 8. In this system, we use eight digits: 0, 1, 2, 3, 4, 5, 6, and 7. Some Native American tribes used this system until the 20th century. Later, the octal system became popular in the early days of computers because it made binary numbers shorter and easier to read.

In octal, one digit is used for three binary digits. This works because 8 is equal to 2 raised to the power of 3 (2³). For this reason, octal was a good way to shorten binary on machines that worked with word sizes in multiples of three, such as 6-bit, 12-bit, 24-bit, or 36-bit. Today, most new systems use hexadecimal instead of octal. However, octal numbers remain an important part of basic electronics.

What are Binary Numbers?

The binary number system uses base 2. It has only two digits: 0 and 1.

The Egyptians, Chinese, and Indians used binary thinking long ago. In the modern world, binary has become the main language of electronics and computers. It works well because it represents the two states of an electrical signal – off (0) and on (1). Binary is also the basis of computer code. Every piece of digital data, even the text you are reading right now, is made up of binary numbers.

Reading binary is simpler than it looks. It is a positional system, where the value of each digit is based on powers of 2. We start from the right at 2⁰. In binary, each digit is called a bit, which is the smallest unit of information in a computer.

How to Convert Octal to Binary

Converting an octal number to binary is very easy because octal is a shorthand way of writing binary. Remember, each octal digit is equal to three binary digits. Therefore, each octal digit will always give three binary bits. You can convert octal to decimal first and then to binary, but there is also a more direct way. Here are the steps to convert octal to binary:

• Step 1: Write the octal number and separate each digit. Each digit in octal corresponds to three binary digits. These three digits are connected to the power of 2. The last digit on the right is equal to 2⁰ (1), the next digit is 2¹ (2), and the left digit is 2² (4). Write these values ​​(4, 2, 1) under the digits.
• Step 2: Check which numbers (4, 2, 1) you need to add together to make your octal digit. For example, if the digit is 6, then 4 + 2 = 6 (1 does not count). If the digit is 2, then only 2 counts while 4 and 1 do not count.
• Step 3: Write 1 under the numbers used (4, 2, 1). Write 0 under the numbers not used.
• Step 4: Read the line of 1s and 0s you wrote from left to right. This gives you the binary form of the octal digit.
