Octal To Hex Conversion

Octal to Hex

Convert numbers from Octal (base 8) to Hex (base 16) number system. 

How it Works?

To use this calculator, follow the below steps:

• Enter the Octal number in the given input box.
• You will see the calculated Hex number in the output box

Base 8 Number System

oct (octal systems

The Octal Number System is another computer and digital numbering system that uses the Base-8 system. Octal numerals can be made from binary numerals by grouping consecutive binary digits into groups of three (starting from the right). 

Each group or set of bits in an octal, binary number has a unique value between 000 (0) and 111 (4+2+1 = 7), and the total amount of bits in an octal, binary number is divided into groups of three.
Including either a 0o prefix or an 8 suffix designates octal numerals.

Octal is base 8.

A Byte [01001010] is the equivalence of 8bits

Base 16 Number System

hex (hexal / hexadecimal system)

Hex means 16. Numbers with base 16 comes under hex number system. It is also called as hexadecimal number system. To represent numbers in this number system it make use of 8 digits only they are digits from 0-9 and letters A-F. 
Hexadecimal is a convenient way to describe binary numbers in computers. Computers only work on the binary system, and a byte is usually defined as eight binary digits. 
One hexadecimal digit can represent the arrangement of four binary digits. Two hexadecimal digits can represent eight binary digits or a byte.

Hexadecimal is base 16.

A Quick Guide to Octal and Hex

Octal (base-8) and hex (base-16) are less common than decimal, but both hold unique value in computing. Octal was historically popular in early computing systems, while hex still sees heavy usage in modern programming contexts.

When Octal Numbering is Useful

You might run into octal when working with file permissions on Unix/Linux systems (e.g., chmod 755). Understanding this notation is crucial for security and administration tasks. You can manage permissions and troubleshoot issues faster by learning to convert octal values quickly.

Why You Need Octal-Hex Conversions

Switching from octal to hexadecimal can come in handy when you’re dealing with network protocols, certain microcontroller registers, or debugging older embedded systems. With an Octal-Hex converter, you can move seamlessly between different numeric notations, ensuring no information is lost or misinterpreted.
