Decimal to Octal

The Best Online Decimal to Octal Number System Conversion Tool

Decimal to Octal Number System Converter


If you’re a regular user of numbers then you must have come across decimal and octal systems. This article discusses the difference between these two systems and how it is necessary to convert decimals into octal systems. 
The decimal to the octal system or just decimal to octal conversion as it’s better known refers to the conversion of any decimal number to its octal equivalent and vice versa. 
Conversion of decimal to the octal system can be useful when you need to perform operations that require conversion from one type of number notation to another one. 
The main advantage of the octal number system lies in the fact that it allows you to use only the digits 0 through 7, which makes conversion easier when you are limited to this small set of characters.


The decimal system is a system of numeration used to represent numbers with base 10. The decimal system is the most widely deployed and most common system of numeration in the world today. It’s so widespread that many people are still learning how to write it correctly, as well as how to read it hence it may be considered one of the most difficult numeric systems for a newcomer to understand.


The octal number system is a numbering system for binary data. It was developed by engineers during WWII to aid in code breakage. Instead of using letters to represent each bit, they used octal numbers. 
These are base 10, with the zero replaced by an “8” and the one replaced by a “1”. The octal number system is used today with digital devices and information technology (IT) professionals all over the world.


The decimal to the octal system or just decimal to octal conversion as it’s better known refers to the conversion of any decimal number to its octal equivalent and vice versa. The decimal system has 10 digits which are represented by the numerals 0,1,2,3,4,5,6,7,8 and 9 while the octal has 8 numerals which are represented by 0,1,2,3,4,5,6 and 7 with A (10), B (11), C (12), and D (13) being absent in this case.

Although numbers in the decimal system are easy to understand and write down, it’s sometimes important to convert them into the octal system, especially if you work with computers and programming languages that use the latter system. This article will discuss some of the advantages of using octal instead of decimals.
Precision is affected by the length of data.

Some factors that affect the precision of decimals include: * Conversion time, which is how long it takes to convert one decimal to octal and back again. The more digits, the more time it will take. * Number of digits in the original number - The more digits there are, the less accurate your conversion will be. * Number of digits in the converted number - The more digits you have in your converted number, the less accurate it will be.

You need to convert your data from decimal to the octal system if you are accessing a Unix-based system like Linux. The conversion process is simple and can be accomplished through the use of commands or programs.


Although this conversion can be done manually as mentioned, the earlier decimal system tends to be easy to understand yet it would be very difficult to convert larger batches of decimal data into an octal system as it would take several hours as well as lots of precision to do it manually. 

Hence we recommend using an online conversion tool like this one to perform your task quickly, precisely, and with guaranteed accurate results.

Follow the given guidelines to generate results within no time:

  • Enter the decimal data that you want to get converted.
  • Press the convert button.
  • Retrieve your desired result.

The generated result you get is error-free and can be placed without any cross-checking. This tool  can perform the function in reverse order also.

The easy-to-use interface needs no expertise as it is designed user-friendly. As the data you enter is a result of your hard work, effort, and precious time so we suggest selecting the tool wisely. This website offers a wide range of many other tools that could be helpful for you. For instance, writing aid tools, text-to-image tools, online calculators, etc.


Some important points that highlight the importance of using decimal instead of octal are:

  • Octal uses a lesser number of digits than decimal systems.
  • Due to the lesser number of digits, it had few to no computational errors.
  • Because of a larger number of data decimal systems occupy more space.
  • The octal system consumes less time in solving a problem than the decimal system.
  • By using the octal system it allocates a proper address number in memory.
  • Octal numbers can easily be converted into the binary language without wasting much time.
  • While working in a digital environment, the octal system uses less circuitry to get information in and out of the system.
  • Decimal data could be difficult to read as the result is generated in larger batches as compared to the octal system.


Anyone who works on computer software and at the back end of an application is aware of the fact that four basic systems are used for developing any software:

  • Binary
  • Decimal, hexadecimal
  • Octal system

These languages had their own set of pros and cons, one had to switch between these different language systems, and for that, the user should be aware of available online conversion tools. The user must be diligent enough to choose tools wisely, to perform their tasks efficiently and accurately.
