What is the largest number this tool supports?

The tool supports numbers up to 999 quadrillion (999,999,999,999,999,999), which covers virtually all practical use cases including astronomical figures.

Does it handle negative numbers?

Yes. Prefix your number with a minus sign (e.g., -42) and the output will read "negative forty-two".

Can I convert decimal numbers?

Yes. Enter a decimal like 3.14 and the tool converts the integer part normally, then reads each decimal digit individually (e.g., "three point one four").

What is the difference between cardinal and ordinal?

Cardinal numbers express quantity: one, two, three. Ordinal numbers express rank or position: first, second, third. Toggle the Ordinal switch to switch between them.

Does this work for numbers like 1,000,000?

Yes. You can include commas as thousands separators in your input — the tool strips them automatically before converting.

Is this tool free to use?

Completely free, runs entirely in your browser, and requires no sign-up or account.
