How Does a Number to Words Converter Work?

Number-to-words conversion relies on programmed rules for each language:

Input Number – Enter the numeric value.

Breaking Down Digits – The tool separates the number into groups (hundreds, thousands, millions).

Mapping – Each group is mapped to its corresponding word (e.g., 1 → one, 1000 → thousand).

Output – Displays the full number in words.

Example:

Input: 1500

Output: One thousand five hundred
