Type a number and see it written out in full — in Brazilian Portuguese, with optional currency format (reais and centavos).
Brazilian documents — checks, invoices, contracts, notarial acts — routinely require numbers written in full. The rule is straightforward but the exceptions are not: "cem" vs. "cento", "mil" vs. "um mil", the placement of "e" between groups, and the agreement of "milhão/milhões", "bilhão/bilhões". Getting any of these wrong in a legal document can void the amount, which is why people look it up instead of writing from memory.
This tool converts any number up to 999 trillion into its full written form in Brazilian Portuguese. In currency mode it adds "reais" and "centavos" with the correct agreement — "um real" but "dois reais", "um centavo" but "dois centavos". The number is processed as whole cents to avoid floating-point rounding, which is the same care a financial system takes.
The conversion runs in your browser. Type the number with dots as thousands separators and a comma as the decimal separator (the Brazilian convention), or without separators — the tool handles both. Nothing is uploaded or stored.
Just "mil". In Brazilian Portuguese, "um mil" is considered incorrect — the standard form is "mil reais", not "um mil reais".
Yes. In currency mode, the decimal part is written as centavos with the correct agreement.
Up to 999 trillion (999.999.999.999.999). Above that, the groups do not have standard names in everyday Brazilian Portuguese.
The text follows the standard Brazilian Portuguese conventions. Verify the result before using it in a legal document — the tool is a writing aid, not a legal service.
No. The conversion runs entirely in JavaScript on your device.
