What are number bases?

A number base is the number of different digits or combination of digits and letters that a system of counting uses to represent numbers. For example, the most common base is Decimal (Base 10), which uses the 10 digits from 0 to 9. Binary (Base 2) uses only 0 and 1, and is the fundamental language of computers.

Is this number converter free?

Yes, this online number base converter is completely free for anyone to use, whether you're a student, a programmer, or just curious.

Why is Hexadecimal (Base 16) used in computing?

Hexadecimal is used because it's a more compact and human-friendly way to represent binary-coded values. One hexadecimal digit can represent four binary digits (bits), making it much easier to write and read long binary strings often found in computer programming.
