Octal to Hexadecimal

Octal to Hexadecimal Converter


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

Here's a brief explanation of both systems:

  • 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).
  • 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).

To convert an octal number to hexadecimal, you typically need to go through the decimal (base-10) conversion as an intermediate step. Here are the general steps:

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

Let's illustrate this with an example:

Suppose you have the octal number 35.

  • Convert it to decimal:
    • 3 * 8^1 + 5 * 8^0 = 24 + 5 = 29 (decimal)
  • Convert the decimal number (29) to hexadecimal:
    • 29 in hexadecimal is 1D.

So, the octal number 35 is equivalent to the hexadecimal number 1D.

You can also use programming languages like Python to perform these conversions automatically.
