Octal to Hexadecimal Conversion


Octal to Hexadecimal conversion is an important operation in digital systems and computing. Octal numbers (base 8) can be directly converted into hexadecimal (base 16), making it easier to represent large binary numbers compactly.

What are Octal Numbers?


Octal numbers use a base of 8, with digits ranging from 0 to 7. This numbering system is commonly used in computing as a shorter way to represent long binary sequences.

What are Hexadecimal Numbers?


Hexadecimal numbers use a base of 16 and include digits from 0 to 9 and letters A to F, where A stands for 10, B for 11, and so on up to F for 15. Hexadecimal is used extensively in programming and computing due to its ability to represent binary data in a more compact form.

Methods to Convert Octal to Hexadecimal


There are two key methods for converting octal numbers to hexadecimal: first converting octal to binary, and then binary to hexadecimal.

Steps for Octal to Hexadecimal Conversion


  1. Convert the octal number into binary, where each octal digit is represented by a three-bit binary number.
  2. Group the binary digits into sets of four, starting from the right (add leading zeros if necessary).
  3. Convert each group of four binary digits into their hexadecimal equivalents using a binary-to-hex table.

Solved Examples of Octal to Hexadecimal Conversion


Example 1: Convert (123)8 to hexadecimal


Binary equivalent of 1238 is 001 010 011. Grouped into fours, it becomes 0001 0100 011. Hexadecimal equivalent is 1 4 3, so (123)8 = (53)16.

Example 2: Convert (4321)8 to hexadecimal


Binary equivalent of 43218 is 100 011 010 001. Grouped into fours, it becomes 0001 0001 1010 0001. Hexadecimal equivalent is 1 1 A 1, so (4321)8 = (11A1)16.

Example 3: Convert (57)8 to hexadecimal


Binary equivalent of 578 is 101 111. Grouped into fours, it becomes 0001 0111. Hexadecimal equivalent is 1 7, so (57)8 = (17)16.

FAQs
