Hexadecimal to Octal

What is a Hexadecimal Number System?

The hexadecimal number system (base 16) uses digits 0-9 and letters A-F. It is commonly used in computing and digital electronics due to its compact representation of binary numbers.

What is an Octal Number System?

The octal number system (base 8) consists of digits 0-7 and is widely used in computer applications, particularly in file permissions and digital systems.

Hex to Octal Conversion Formula

If you prefer a mathematical approach:

Octal=∑(Hex digit×16 n )mod8

Where:

• 𝑛 n is the position of the hex digit from the right (starting at 0).
• Convert the decimal result to octal.

To manually convert a hexadecimal number to octal:

• Convert Hexadecimal to Binary
  • Each hex digit corresponds to a 4-bit binary equivalent.
  • Example: A3 (Hex) → 1010 0011 (Binary)
• Group Binary Digits into Triplets (Right to Left)
  • Since octal is base-8, group the binary digits in sets of three.
  • Example: 1010 0011 → 1 010 001 011
• Convert Each Triplet to Octal
  • Convert each three-bit group to its octal equivalent.
  • Example: 1 010 001 011 → 1 2 1 3 (Octal)

However, manual conversion can be time-consuming and error-prone. Our tool automates this process for you!
