Hexadecimal vs Octal: Number System Comparison

Understanding the differences between hexadecimal and octal number systems

Hexadecimal System

Base-16 system (0-9, A-F)
Each digit represents 4 binary digits
Compact representation of binary data
Widely used in programming and computing

Example:

Hex FF = 15×16¹ + 15×16⁰ = 255 decimal

Best for:

Memory addresses, color codes, debugging, low-level programming

Octal System

Base-8 system (0-7)
Each digit represents 3 binary digits
Alternative compact binary representation
Used in Unix file permissions

Example:

Hex FF = 255 decimal = Octal 377

Best for:

File permissions, legacy systems, embedded programming

Why Convert Hex to Octal?

Cross-platform compatibility
Unix file permissions
Different binary groupings
Legacy system support
Educational purposes
System administration

Frequently Asked Questions

Everything you need to know about hex to octal conversion

What is hex to octal conversion?

Hex to octal conversion transforms hexadecimal numbers (base-16, using digits 0-9 and A-F) into octal numbers (base-8, using digits 0-7). This conversion is useful in programming and digital systems.

How do you convert hex to octal manually?

First convert hex to decimal by multiplying each digit by its power of 16, then convert decimal to octal by repeatedly dividing by 8. For example: hex 2F = (2×16¹ + 15×16⁰) = 47 decimal = 57 octal.

Why convert hexadecimal to octal?

Both hex and octal are compact representations of binary data. Converting between them is useful in programming, system administration, and digital electronics where different number bases are preferred for different purposes.

Can I input hex with 0x prefix?

Yes, our converter automatically handles both formats. You can input hex numbers with or without the '0x' prefix. For example, both 'FF' and '0xFF' are valid inputs.

What's the relationship between hex and octal?

Both hexadecimal and octal are positional number systems that provide compact ways to represent binary data. Hex uses base-16 (4 bits per digit) while octal uses base-8 (3 bits per digit).
