Octal to Decimal

When dealing with number systems, particularly in computer science or mathematics, converting between different bases is a common task. Octal (base-8) and decimal (base-10) are two such numeral systems frequently encountered, especially in computing.

Octal numbers are expressed using digits ranging from 0 to 7, whereas decimal numbers utilize digits from 0 to 9. The process of converting octal numbers to decimal involves understanding the positional value system and performing simple calculations.

How to Convert Octal to Decimal

To convert an octal number to its decimal equivalent, follow these steps:

1. Write Down the Octal Number: Begin by writing down the octal number you want to convert.

2. Assign Powers of 8: Starting from the rightmost digit, assign powers of 8 to each digit's position, increasing from right to left (e.g., 8^0, 8^1, 8^2, and so on).

3. Multiply and Sum: Multiply each digit of the octal number by the corresponding power of 8 and sum the results.

4. Get the Decimal Equivalent: The sum obtained in the previous step is the decimal equivalent of the octal number.

Example:

Let's convert the octal number 347 to decimal:

Therefore, the decimal equivalent of 347 in octal is 231.
