Convert any amount to words instantly, perfect for checks, invoices and contracts
Decimals are written as on checks: “and 50/100”.
Convert any number to words instantly: type the amount and get text ready to copy. It's the fastest way to fill out checks, invoices, promissory notes, receipts and contracts, where the amount must also appear in words. Decimals are written in check format (“and 50/100”), you can get the result in uppercase, and you can choose between English, Spanish, Portuguese, French, German and Italian.
The result appears as you type:
Type the amount, with or without a thousands separator: 1250, 1,250 or 1,250.50.
Choose the output language if you need it in another language.
Check the uppercase option if it's for a check or a formal document.
Click Copy and paste the text wherever you need it.
Standard US style is applied: numbers from 21 to 99 are hyphenated (twenty-one, ninety-nine), and no “and” is used after “hundred” (one hundred fifty, one thousand two hundred fifty).
Cents are written as a fraction of 100 (“and 50/100”), the usual format on checks and invoices. They are rounded to two decimal places.
Converts numbers from 0 to 999,999,999,999, including negatives. Accepts a period or a comma as the thousands or decimal separator.
Writing amounts in words prevents mistakes and tampering:
Checks: the amount in words is the one that prevails if it doesn't match the amount written in numbers.
Invoices and receipts: many regulations require the total in words as well.
Contracts and promissory notes: amounts in words prevent them from being altered by adding digits.
Schoolwork: check how numbers are correctly written in words.
On checks, write the amount in words using the whole line and finish with a line so nothing can be added.
Turn on uppercase for formal documents: it's harder to alter.
Add the currency yourself if you need it, for example “dollars” or “euros”, because it varies by country.
Always check that the figure and the text match before signing.
One thousand two hundred fifty and 50/100. Type it in the tool and you'll get it ready to copy, in uppercase too.
In US style, no: write “one hundred fifty,” not “one hundred and fifty.” The “and” is reserved for the cents on a check (“and 50/100”). The tool applies this rule automatically.
Up to 999,999,999,999 (nine hundred ninety-nine billion nine hundred ninety-nine million…), more than enough for any document.
Yes. Choose the output language: English, Spanish, Portuguese, French, German or Italian.
