Number to Words (Portuguese)
Convert numbers to words in Portuguese (por extenso). Supports positive and negative integers and values up to hundreds of millions.
How does number-to-words conversion work?
First the number is broken down into groups of hundreds, tens and units. Each group gets the right Portuguese connectors ("e", "mil", "milhão", "bilhão"). Special cases get their own treatment, like the exact "cem" as opposed to "cento" followed by something more.
The covered range runs from −999,999,999,999 to 999,999,999,999, always with integers. Everything is converted in the browser itself.
Write numbers in words
Cheques, contracts and documents ask for the number written out, and a spelling slip looks careless. Type the value and this tool returns the version written in words, in Portuguese.
The details that trip most people up are handled for you: the plurals, the joins with "e", negative numbers and values with decimal places. So instead of puzzling over how to write "mil duzentos e trinta e quatro" properly, you type the number and copy the finished result.
Handy for filling in a document, double-checking a spelling or teaching how to read numbers, and the conversion runs in the browser without sending anything out.
