How Brazilian Portuguese number words work

Cem and cento

Exactly 100 is cem. With a remainder, use cento: 101 is cento e um and 126 is cento e vinte e seis. Hundreds include duzentos, quinhentos and setecentos.

Where e belongs

Within a three-digit group, e joins hundreds, tens and units. Compare 1100, mil e cem, with 1101, mil cento e um. This tool joins the last two nonzero groups with e when the final coefficient is below 100 or an exact hundred. Other group boundaries use spaces; editorial punctuation and conjunction choices can vary.

Mil, milhão and the Brazilian short scale

1000 is mil, without um. Larger scale nouns have singular and plural forms: um milhão, dois milhões. In Brazil, bilhão is 10⁹ and trilhão is 10¹². These follow the English short scale; European Portuguese uses different large-number conventions.

Brazilian spelling and grammatical scope

The output uses dezesseis, dezessete and dezenove. For 14 this tool chooses catorze; quatorze is also accepted. Accents are preserved, as in três and milhão. Standalone masculine forms do not automatically supply feminine noun agreement, currency wording or ordinals.

Negatives, decimals and separators

A negative value starts with menos. Decimal digits are read one by one after vírgula: 12,05 becomes doze vírgula zero cinco. Leading and trailing fractional zeros are kept. Both a comma and a point mean a decimal mark in this input; use spaces to group thousands. This explicit input convention differs from Brazilian formatting that uses points for thousands.
