Why Convert Octal To Decimal?
Converting octal to decimal is necessary when you want to represent a number originally expressed in octal (base8) in the decimal (base10) system. The decimal system is the most commonly used numeral system, and it is the standard way we represent numbers in everyday life.
Here's a brief explanation of the two numeral systems:

Octal (Base8): This numeral system uses eight digits, namely 0, 1, 2, 3, 4, 5, 6, and 7. Each digit's place value is a power of 8. For example, in the octal number 753, the rightmost digit represents 3 ones, the middle digit represents 5 eights (5 * 8), and the leftmost digit represents 7 sixtyfours (7 * 64).

Decimal (Base10): This is the standard numeral system used by humans, and it includes the digits 0 through 9. Each digit's place value is a power of 10. For example, in the decimal number 123, the rightmost digit represents 3 ones, the middle digit represents 2 tens (2 * 10), and the leftmost digit represents 1 hundred (1 * 100).
When you convert an octal number to decimal, you are essentially expressing the same quantity using the decimal system instead of the octal system. This conversion can be useful in various computing and mathematical contexts where decimal representation is more common and practical.
The conversion process involves multiplying each digit in the octal number by the corresponding power of 8 and summing up the results. The resulting sum is the equivalent decimal representation of the original octal number.
