Number to Indonesian Words

In words

Rupiah amounts are often written in words on invoices. A comma or dot marks the decimals, which are read one digit at a time.

About this tool

Write an amount in Indonesian words, the way it is done on an invoice or a cheque. Enter a number and the page spells it out, grouping by ribu, juta, miliar and triliun, with an optional capital first letter. Decimals are read one digit at a time after the word koma.

Questions

How is 1,250,000 read?
As satu juta dua ratus lima puluh ribu. The scale words are spoken in order from the largest group to the smallest, the same way the digits are written.
What about the number one?
In front of a scale word it shortens: 1000 is seribu and 100 is seratus, not satu ribu and satu ratus. Everywhere else it stays satu, as in satu juta.
How large a number can it handle?
Up to sixteen digits, which covers kuadriliun. Past that the exact value can no longer be held as a number in the page, so the tool asks for a smaller one instead of printing something wrong.
