Frequently asked questions
What does "number to words" mean?
It is the textual form of a digit sequence. "1,234" becomes "one thousand two hundred thirty-four". Banks, accountants and lawyers write the amount both ways on cheques and invoices so a tampered digit cannot change the contract.
Which languages are supported?
English, Russian, Korean, Arabic, Indonesian and Portuguese — all with native grammar rules, not a dictionary lookup. Russian uses the right gender ("одна тысяча" feminine, "два миллиона" masculine) and the "один / два / пять рублей" plural cascade; Korean handles 만 (ten thousand) and 억 (hundred million); Arabic produces proper dual and plural forms.
Does it handle currency and cheques?
Yes. Pick a currency (USD, EUR, GBP, RUB, JPY, CNY, KRW, INR, AUD, CAD, BRL, IDR), choose how to write the fractional part (words / fraction like 56/100 / "point five six") and enable "only" suffix for cheques. A visual cheque preview is rendered under the result.
How big a number can I convert?
Up to 30 digits before the decimal point — that covers nonillion and beyond, far more than any real-world document needs. Decimals are kept to the precision of the chosen format: 2 for currency, up to 10 for plain numbers.
Can I convert many numbers at once?
Open the Batch panel, paste one number per line and press Process. You get a table with the spelled-out form for every row and a CSV download button — handy for invoice registers or accounting ledgers.
How does the converter work technically?
