Hexadecimal to Octal

Hexadecimal to Octal Converter


A Hexadecimal to Octal Converter is a free online tool that helps you convert numbers from the hexadecimal number system to the octal number system. Both hexadecimal and octal are different base systems used in mathematics and computing.

Here's a brief explanation of both systems:

  • Hexadecimal (Base-16):
    • The hexadecimal number system uses sixteen digits: 0-9 and A-F (where A stands for 10, B for 11, C for 12, D for 13, E for 14, and F for 15 in decimal).
    • Hexadecimal is commonly used in computer science and programming because it can represent large binary values compactly.
    • For example, in hexadecimal, the number 1A is equivalent to binary 00011010 (or decimal 26).
  • Octal (Base-8):
    • The octal number system uses eight digits: 0, 1, 2, 3, 4, 5, 6, and 7.
    • Each digit in octal represents three binary digits (bits), making it useful in computer science for representing groups of binary digits conveniently.
    • For example, in octal, the number 12 is equivalent to binary 010010 (or decimal 10).

To convert a hexadecimal number to octal, you typically need to go through an intermediate step, which is converting to binary, and then converting the binary result to octal. Here are the general steps:

  • Convert the hexadecimal number to binary.
  • Convert the binary number to octal.

Let's illustrate this with an example:

Suppose you have the hexadecimal number 1A.

  • Convert it to binary:
    • 1 in hexadecimal is 0001 in binary.
    • A in hexadecimal is 1010 in binary.
  • Combine the binary equivalents:
    • 00011010
  • Convert the binary number to octal (in groups of three bits from right to left):
    • 00 011 010

So, the hexadecimal number 1A is equivalent to the octal number 32 in octal notation.

You can use online converters or programming languages like Python to perform these conversions automatically, especially when dealing with longer hexadecimal numbers.
