What language are the words in?

Always American English, on every locale of this page. Spanish, Portuguese, French, and German translate the labels and FAQ, but 123 still becomes one hundred twenty-three. That keeps checks, invoices, and English-language forms consistent.

Do you write and like British English?

No. 101 is one hundred one, not one hundred and one. Hyphens are used in compounds such as twenty-one.

Can I convert decimals and negatives?

Yes. Decimals use point plus one word per digit (3.05 → three point zero five). Trailing zeros after the point are dropped. Negatives start with minus.

How large a number can I convert?

The integer part can have at most 15 digits (up to 999 trillion). Grouping commas are stripped first. Scientific notation such as 1e6 is not accepted.

Is my number uploaded?

No. Conversion runs entirely in your browser. Nothing you type is uploaded, logged, or stored.
