Number to Words
- Type the number.
- Choose the output language: Portuguese or English.
- If it is a monetary value, pick the currency — real, dollar or euro. With no currency, you get the plain number in words.
- Adjust the decimal places when the value has cents or a fraction.
- Cheques: the written amount prevails over the numeric one if they disagree.
- Contracts and powers of attorney: long-standing practice to stop a single digit being altered.
- Promissory notes and credit instruments: a formal requirement.
- Legal filings: a convention of legal drafting.
English inserts "and" before the final group in British usage — "two hundred and thirty-four" — while American usage often drops it. Both are read the same way.
Tens and units are joined by a hyphen from twenty-one upward: thirty-five, ninety-nine.
The scale follows the short form: thousand, million, billion, trillion, quadrillion. A billion here is a thousand million, matching modern usage in English and Brazilian Portuguese alike.
With a currency, the whole and fractional parts get distinct names — dollars and cents — and plural agreement is applied to each part separately.
Conversion reaches the quadrillion scale. Numbers beyond that have no settled naming and are not covered.
Output is available in Portuguese and English. Spanish is not, because its scale naming differs and an approximate translation would produce wrong values in a formal document.
