What this converter does
It spells numbers the way they are written in American English: “one thousand two hundred thirty-four”, with hyphens from twenty-one to ninety-nine and without “and” inside whole numbers. Check mode adds the cents as a fraction over 100, which is how most US checks are filled in. Ordinal mode gives position words such as “twenty-first”.
How to write a check, field by field
Fill in the date, the name of the person or company after “Pay to the order of”, the amount in numbers in the box, and the same amount in words on the line below. Add a memo if you want a reminder or an account number, and sign on the bottom right. Keep a record of the check number, date and amount in your register or banking app.
- Date: the day you write the check.
- Pay to the order of: the exact name of the payee.
- Numeric box: 1,234.56, written close to the dollar sign.
- Amount line: One thousand two hundred thirty-four and 56/100, then a line to the end.
- Memo: optional note, such as an invoice or account number.
- Signature: sign the way your bank has it on file.
When words and numbers disagree
The Consumer Financial Protection Bureau explains that when the words and the numbers on a check differ, the amount spelled out in words is used. That makes the written line the one to double-check. Start it at the far left and fill the empty space with a line so nothing can be added.
Writing cents and round amounts
Cents go after “and” as a fraction over 100: “and 05/100” for five cents and “and 00/100” for a round amount such as $1,500. Some people prefer to write the cents in words; both styles are shown here. For amounts under one dollar, a common format is “Zero and 75/100”, so the dollar part of the line is not blank.
American style: “and”, hyphens and capitals
In American usage “and” is reserved for the decimal point or the cents on a check, so 120 is “one hundred twenty”, while British English often says “one hundred and twenty”. Numbers from twenty-one to ninety-nine take a hyphen. Capitalizing only the first word keeps the line easy to read; writing the whole line in capital letters is also common on checks.
Decimals and ordinal numbers
Outside of checks, decimals are read digit by digit after the word “point”: 3.14 is “three point one four”. Ordinal words describe position rather than quantity. Most add “th”, but first, second, third, fifth, eighth, ninth and twelfth are irregular, and tens ending in “y” change to “ieth”, as in twentieth.

Frequently asked questions
How do you write $1,500 on a check?
Write 1,500.00 in the box and “One thousand five hundred and 00/100” on the amount line, then draw a line to the printed word DOLLARS.
How do you write cents on a check?
Put the cents after “and” as a fraction over 100, such as “and 56/100”. The fraction always has two digits, so five cents is 05/100.
What if the words and the numbers on a check are different?
According to the CFPB, the amount spelled out in words is used. Make sure the written line matches the box before you sign.
Do I write “and” in whole numbers?
Not in American English. “And” marks the decimal point or the cents, so 120 is “one hundred twenty”.
Where do hyphens go when writing numbers?
Use a hyphen for the numbers twenty-one through ninety-nine, including inside larger numbers, such as “three hundred forty-five”.
How large a number can I convert?
Whole numbers up to 999 trillion. Check amounts must be below one trillion dollars and use at most two decimal places.
How are decimals read?
Digit by digit after “point”, so 0.25 is “zero point two five”. For money, use check mode to read the cents.
What to keep in mind
Check the spelling against the numeric box before signing. If the words and the numbers on a check do not match, the amount in words is the one normally used.
