Frequently asked questions
▸How large a number can I convert?
Whole numbers from 0 to 999,999,999,999,999 — that is 999 trillion — plus decimals with any number of digits. Anything larger is rejected instead of being silently rounded.
▸Why is there no 'and', as in one hundred and five?
The output follows the American short-scale style used on cheques and invoices: 'one hundred five', with hyphens in compound tens such as 'forty-two'.
▸Why is the result always in English?
The tool is built for English paperwork — invoices, cheques, contracts and wire transfers, where amounts must be spelled out. The interface still follows your language.
