Number to Words Converter - Cardinal, Ordinal & Check Writing

Cardinal numbers

Cardinal numbers express quantity and are the most common form: one, two, three, forty-two, one thousand. They answer "how many?" and are used in everyday counting, measurements, and mathematical expressions.

Ordinal numbers

Ordinal numbers express position or rank in a sequence: first, second, third, forty-second. They answer "which position?" and are used in dates ("January 1st"), rankings ("2nd place"), and enumerations.

Check-writing format

When writing a check, the dollar amount must be spelled out to prevent fraud and ambiguity. The format is: "[dollars in words] and XX/100". For example, a check for $1,234.56 reads "One thousand, two hundred thirty-four and 56/100". This converter generates that line automatically.

International number naming differences

The word "billion" means different things in different countries. In the short scale (used in the US, Canada, UK since 1974, and most English-speaking countries), a billion = 10⁹ (one thousand million). In the traditional long scale (historically used in much of Europe and Latin America), a billion = 10¹² (one million million - what the short scale calls a trillion).

This difference has caused real confusion in scientific and financial contexts. When translating large numbers across languages, always verify which scale is being used.

Large number names

Locale-specific formats

• German: uses "Komma" for the decimal separator (3,14 = three point fourteen) and no "and" connector in large numbers.
• British English: uses "and" before the tens in hundreds: "one hundred and thirty-four" (American English typically omits "and": "one hundred thirty-four").
• French: uses multiplication for some numbers - soixante-dix (sixty-ten = 70), quatre-vingts (four-twenties = 80), quatre-vingt-dix (four-twenty-ten = 90). Belgian and Swiss French use septante, octante/huitante, and nonante instead.
