Octal to Decimal
Octal to Decimal Converter
An Octal to Decimal converter is a free online tool used to convert numbers from the octal numeral system to the decimal numeral system.
Here's a brief explanation of each numeral system:
- Octal (Base-8): Octal is a positional numeral system that uses 8 as its base. It uses the digits 0-7 to represent numbers. For example, in octal, the number 10 is equivalent to the decimal number 8, and the number 20 is equivalent to the decimal number 16.
- Decimal (Base-10): Decimal is the most common numeral system used worldwide. It uses 10 as its base, with digits 0-9 to represent numbers.
To convert an octal number to decimal, you can use the following steps:
- Write down the octal number you want to convert.
- Assign a positional value to each digit in the octal number, starting from the right and increasing by a power of 8 for each position. The rightmost digit is in the 8^0 position, the next digit to the left is in the 8^1 position, the next in the 8^2 position, and so on.
- Multiply each digit in the octal number by its positional value.
- Sum up all the products obtained in step 3 to get the decimal equivalent.
Here's an example:
Octal number: 356
- The rightmost digit is 6, which is in the 8^0 position.
- The middle digit is 5, which is in the 8^1 position.
- The leftmost digit is 3, which is in the 8^2 position.
Now, we calculate the decimal equivalent:
- Decimal = (3 * 8^2) + (5 * 8^1) + (6 * 8^0)
- Decimal = (3 * 64) + (5 * 8) + (6 * 1)
- Decimal = 192 + 40 + 6
- Decimal = 238
So, the octal number 356 is equivalent to the decimal number 238.
