What is Octal?

Octal is a base 8 number system that uses 8 digits, 0-7. Octal numbers are commonly used in computer systems and digital electronics because they have a very simple relationship to binary numbers.

Every octal digit corresponds to three binary digits, making it easy to convert between the two number systems. For example, the octal number 1234 can be represented as the binary number 10011010010.

To convert an octal number to a decimal number, simply multiply each octal digit by its corresponding power of eight and add up all the results. For example, the octal number 1234 would be equal to 1*8^3 + 2*8^2 + 3*8^1 + 4*8^0 = 908.

How to convert Octal to Decimal ?

Converting octal to decimal is a common task when working with computers. While most programming languages have built-in functions to convert between the two number formats, it's still useful to understand how the conversion works.

The easiest way to convert an octal number to decimal is by using the "divide and conquer" method. Start by dividing the octal number by 10. The remainder will be the first digit of the decimal equivalent. Repeat this process, dividing the previous quotient by 10 until you reach 0. The last quotient will be the most significant digit of the decimal equivalent.

For example, let's convert the octal number 43 to decimal:

43 / 10 = 4 with a remainder of 3
4 / 10 = 0 with a remainder of 4
0 / 10 = 0 with a remainder of 0

Therefore, the decimal equivalent of 43 is 434.
