How to Convert Octal to Hexadecimal

To convert an octal number to hexadecimal, you should first convert it to a binary number and then from binary to hexadecimal. Follow these steps:

Conversion Steps:

  1. Start with your octal number. For example, let's use the octal number 345.
  2. Convert the octal number to binary. Replace each octal digit with its binary representation. In this case:
    • 3 (octal) is equal to 011 (binary).
    • 4 (octal) is equal to 100 (binary).
    • 5 (octal) is equal to 101 (binary).
  3. Group the binary digits in sets of 4 from right to left. Add leading zeros if necessary. In this case, it becomes 0011 1001 0101 (binary).
  4. Convert the grouped binary to hexadecimal. In this example, 0011 is 3 in hexadecimal, 1001 is 9, and 0101 is 5. So, the hexadecimal representation is 395.

That's it! You've successfully converted an octal number to hexadecimal.
