You can see that by using this tool we have converted an octal number 234_{8} into a decimal number.

**It gave the result of 156 _{10}.**

Now we will calculate manually and check the result of both.

How to convert octal numbers into decimal numbers manually?

Unlike using a converter, manual conversion is a hectic task as you have to perform a lot of calculations.

**Consider an example: **

We have an octal number: 234_{8 }

Now we have to convert it into decimal, we will multiply each digit by 8 while reducing the power of 8 according to the position of the number.

234_{8} = 2*8^{2}+3*8^{1}+4*8^{0} = 2*64+24+4 = 128+24+4 = 156

**156 _{10} is our required decimal number.**

As the result of both is the same, so we conclude that our tool is the best way to convert octal numbers into decimal because it saves your time.

There are some reasons why you should use this automated tool:

Octal numbers are known as base-8 numbers comprising of 8 digits from 0-7. Each number has a weightage of 8 that implies that each preceding digit is eight times powerful than the previous one.

When converted to binary each octal number is represented in the form of three. For example, if we convert 34_{8 }into binary, we will write 011100_{2 }in binary form. Because 3_{8} = 011_{2} and 4_{8} = 100_{2}.

Octal numbers had been extensively used in computing till the advent of the hexadecimal number system. As you know, computers understand binary language, so octal numbers were an easy way to convert them into binary for it needs fewer calculations as compared to other number systems.

At a certain time, the CPU used 26 and 36 bits for calculations therefore it was easy for computers to use an octal number system.

In the aviation industry, these numbers are used to direct ground radars system about airplane identification and air pressure. Transponders use them as 4 digits octal numbers.

These 0 to 7 octal numbers are used for file permissions of your website hosted on pair networks in the Linux operating system.

The decimal number system is known as the base-10 number system comprising 10 digits starting from 0-9 successively. Each digit has a significance of 10. People have been using these digits for a long time.

Fractions are denoted by points in this number system. Each position starts from left to right as units, tens hundreds, thousands, and so on.

We have been using the decimal number system from time immemorial. We can infer that it developed from its ease to count things such as we have ten fingers, so it was easy to do arithmetic.

In our daily life, we use decimal number systems in many ways such as currency, measurements, and many more.
