Frequently Asked Questions

What is Number Base Converter and what is it used for?

A number-base converter changes a number between bases such as binary (2), decimal (10), octal (8), and hexadecimal (16).

Enter a valid number for the source base and choose the destination base. The converter applies positional-number rules.

Each digit’s allowed range depends on the base: for example, hexadecimal permits 0–9 and A–F.

Conversion does not change the underlying numeric value; it changes its representation.

It is useful in programming, networking, digital electronics, and learning how positional number systems work.

An invalid digit for the selected source base is a common reason for errors.
