Octal to Decimal converter


How to convert Octal to Decimal:

A regular decimal number is the sum of the digits multiplied with 10n.

Example:

137 in base 10 is equal to each digit multiplied with its corresponding 10n:

13710 = (1 * 102) + (3 * 101) + (7 * 100)

= 100 + 30 + 7

Octal numbers are read the same way; however each digit counts 8n instead of 10n.

Multiply each digit of the hex number with its corresponding 8n.
