Frequently Asked Questions about Number to Words Converter
- 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.
