Base Converter Tool

Base conversion is the process of converting numbers between different number systems. The most common bases include binary, octal, decimal, and hexadecimal.

What is Base?

Base is a way of counting that represents how many different digit symbols can be used in each position. For example:

  • Binary (Base-2): Uses 2 digits - 0 and 1
  • Octal (Base-8): Uses 8 digits - 0 through 7
  • Decimal (Base-10): Uses 10 digits - 0 through 9
  • Hexadecimal (Base-16): Uses 16 characters - 0-9 and A-F

Why Different Bases?

  • Binary is the fundamental language of computers, as circuits only have two states: on (1) and off (0)
  • Octal and hexadecimal can represent binary numbers more concisely
  • Decimal is the most natural counting system for humans
  • Hexadecimal is widely used in programming for colors, memory addresses, etc.
