What is Radix Conversion?

Radix conversion is the process of converting a number from one numeral system representation to another. Different radix systems use different bases and symbol sets to represent numbers.

1
Binary (base-2): Uses only 0 and 1, fundamental for computer internal data storage
2
Octal (base-8): Uses digits 0-7, commonly used for file permissions representation
3
Decimal (base-10): The most commonly used numeral system in daily life
4
Hexadecimal (base-16): Uses 0-9 and A-F, widely used in programming and color representation

Radix Systems Explained

2

Binary

The fundamental numeral system used internally by computers, all data is ultimately stored in binary form

Used Characters: 0, 1
8

Octal

Commonly used for Unix/Linux system file permission representation, is 2 to the power of 3

Used Characters: 0, 1, 2, 3, 4, 5, 6, 7
10

Decimal

The standard numeral system used by humans in daily life, based on counting with 10 fingers

Used Characters: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
16

Hexadecimal

Widely used in programming, particularly suitable for representing byte values and color codes

Used Characters: 0-9, A, B, C, D, E, F

Pro Tips

  • Letters A-F in hexadecimal are case-insensitive, but output is uniformly uppercase
  • Binary numbers are commonly used to represent switch states and logical operations
  • Octal is very common in Unix/Linux file permissions, like 755, 644, etc.
  • Hexadecimal is particularly suitable for representing color values, like #FF0000 for red
  • In computers: 1 byte = 8 bits = maximum value 255(decimal) = FF(hexadecimal)
  • You can use example buttons to quickly load common test data
