Number to Words Converter (English, Portuguese, Spanish, French)

What this tool does

Spelling out numbers is where languages differ most. American English writes 1 234 as one thousand two hundred thirty-four, with no 'and'; Portuguese puts 'e' only before the last group when it is under a hundred or a round hundred, so mil e duzentos but mil duzentos e trinta; Spanish turns uno into un before nouns, as in veintiún euros; and French keeps the s of quatre-vingts and deux cents only at the end, writing quatre-vingt mille. Large numbers follow the long scale in Portuguese, Spanish and French, where a billion is a million millions, and mil milhões is 10⁹. For money, the cents are written too, and amounts of whole millions take 'de' (um milhão de euros).

Formula

the number is split into groups of three digits, each read with the name of its order (thousand, million, billion, trillion)
