Octal to HEX

Octal to HEX Converter Online

The Octal to HEX Converter lets you quickly convert octal numbers into hexadecimal (HEX) format without any manual effort. Whether you're working in embedded systems, computer architecture, or educational settings, this tool helps eliminate conversion errors and speeds up your workflow.

What is Octal to HEX Conversion?

Octal (base-8) and Hexadecimal (base-16) are two popular number systems used in computing and digital electronics. Octal uses digits 0–7, while hexadecimal uses 0–9 and A–F. Converting between them allows engineers, programmers, and students to represent and interpret values more efficiently, especially at the hardware level.

How to Use the Octal to HEX Converter Tool?

1. Enter an octal number into the input box.
2. Click the Convert button.
3. Instantly receive the converted hexadecimal value.

Example: Octal to HEX Conversion

Input: 456  
Output: 12E

This conversion is done in real-time using accurate number system logic without needing manual steps.

Convert Octal to HEX Manually (Conversion Method)

If you’re interested in understanding the manual method, follow this step-by-step guide:

1. Convert the octal number to binary (each octal digit = 3 binary bits).
2. Group binary digits into 4-bit segments (starting from the right).
3. Convert each 4-bit binary group into a hexadecimal digit.

Example: Convert Octal 456 to HEX

Step 1: Octal 456 → Binary: 100 101 110  
Combined: 100101110  
Step 2: Group as 4-bit from right: 0001 0010 1110  
Step 3: Convert to HEX: 1 2 E  
Final HEX: 12E
