The octal system (base-8) uses digits 0 through 7, while the hexadecimal system (base-16) uses digits 0–9 and letters A–F. Converting octal to hexadecimal is a two-step process that first involves converting the octal number to binary, then converting the binary number to hexadecimal.

Conversion Method

Steps to Convert

  1. Convert the octal number to binary by replacing each octal digit with its 3-bit binary equivalent.
  2. Group the binary digits into groups of four bits (starting from the right) and convert each group to hexadecimal using a reference table.

Example

Convert 7318​ (octal) to hexadecimal:

Convert each octal digit to binary:

7 = 111
3 = 011
1 = 001

Binary result: 111 011 001

Group the binary digits into groups of four (add leading zeros if necessary): 0001 1101 1001

Convert each group to hexadecimal:

0001 = 1
1101 = D
1001 = 9

Combined result: 1D916

Result: 7318 = 1D916
