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?
Enter 1250000 without separators. The output is satu juta dua ratus lima puluh ribu. Typing 1,250,000 is not the same input here: commas mark decimal digits, not thousands.
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?
The tool rejects an integer part longer than 16 digits. That length check is not a promise that every shorter integer is exact: JavaScript numbers can lose precision above 9007199254740991. Double-check large financial amounts before using the words.
