* Hex - Octal Converter* is an online tool to perform conversion between octal & hex number systems in digital electronics & communications. The numbers & alphabets 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E & F are known as hexadecimal numbers and represented by base-16 notation. Whereas, the digits 0, 1, 2, 3, 4, 5, 6 & 7 are known as octal numbers generally represented by base-8 notation. The solved example problems & conversion table may useful to understand how to do such hex - octal conversions manually. By using this converter user may find the equivalent octal or hex numbers for the hex or octal input respectively by slecting the appropriate radio button & supplying the respective inputs.

One of the easiest conversion in digital electronics & communications. Follow the below steps to perform hex to octal number conversion.

__step 1:__ Separate the digits of the given hex number, if it contains more than 1 digit.

__step 2:__ Find the equivalent binary number for each digit of octal number. Add 0's to the left if any of the binary equivalent is shorter than 4 bits.

__step 3:__ Write the all groups binary numbers together, maintaining the same group.

__step 4:__ Separate the binary digits into groups, each containing 3 bits or digits from right to left. Add 0s to the left, if the last group contains less than 3 bits.

__step 5:__ Find the octal equivalent for each group.

__step 6:__ Write all octal equivalent of each digit together where keeping the same order provides the octal equivalent for the given hexadecimal.

**Solved Example Problem**

The below solved example problem may useful to understand how to perform hex to octal number conversion.

**Example Problem**

Convert the Hexadecimal (B 5 A)_{16} to its octal equivalent.

Similarly, the octal to hex number conversion can be done by following the below steps.

__step 1:__ Separate the digits of the given octal number, if it contains more than 1 digit.

__step 2:__ Find the equivalent binary number for each digit of octal number. Add 0's to the left if any of the binary equivalent is shorter than 3 bits.

__step 3:__ Write the all groups binary numbers together, maintaining the same group order.

__step 4:__ Separate the binary digits into groups, each containing 4 bits or digits from right to left. Add 0s to the left, if the last group contains less than 4 bits.

__step 5:__ Find the hex equivalent for each group.

__step 6:__ Write all hex equivalent of each digit together where keeping the same order provides the hexadecimal equivalent for the given octal number.
