What is Number Base Converter?
The Number Base Converter is a tool that translates numbers between different positional numeral systems. The most common systems in computing are Binary (Base 2), Octal (Base 8), Decimal (Base 10), and Hexadecimal (Base 16). This tool allows you to enter a number in any of these formats and instantly see its equivalent in all the others. It's an indispensable utility for programmers working with low-level code, memory addresses, or color codes.
