Octal to Hexadecimal Converter
An Octal to Hexadecimal Converter helps convert octal numbers (base-8) into hexadecimal numbers (base-16). This conversion is useful in computer science, digital electronics, and number system studies.
Convert the octal number to binary (3-bit groups), then regroup the binary digits into 4-bit groups and convert them into hexadecimal values.
What Is the Octal Number System?
The octal number system is a base-8 number system. It uses digits from 0 to 7. Each octal digit maps directly to a 3-bit binary number.
What Is the Hexadecimal Number System?
The hexadecimal number system is a base-16 number system. It uses digits 0–9 and letters A–F. Hexadecimal is compact and widely used in computing.
How to Convert Octal to Hexadecimal
- Write the octal number
- Convert each octal digit into a 3-bit binary value
- Group the binary digits into sets of 4 from right to left
- Convert each 4-bit group into hexadecimal
- Combine the hexadecimal digits
Example: Convert 50 (Octal) to Hexadecimal

FAQ on Octal to Hexadecimal Converter
Octal to hexadecimal conversion is the process of converting a base-8 number into a base-16 number, usually by converting through binary.
Binary is used because octal digits map to 3 binary bits and hexadecimal digits map to 4 binary bits, making conversion accurate and easy.
The easiest way is converting octal to binary first, then grouping the binary digits into 4-bit sets and converting them into hexadecimal values.
