Common use cases
Checks and payment memos
Write an amount in words next to the numerals so a check or remittance slip matches the figure.
Invoices and contracts
Spell out a total or a quantity so a PDF, email, or printed form is harder to alter.
Classroom and spelling practice
Show how 21 becomes twenty-one and 1,000,000 becomes one million without looking up a chart.
English-language forms on any locale
Use the Spanish, Portuguese, French, or German page and still get English words for a US or UK form.
Examples
- Twenty-one: 21 becomes twenty-one. Compound numbers from 21 to 99 use a hyphen.
- One thousand two hundred thirty-four: 1,234 or 1234 becomes one thousand two hundred thirty-four.
- Decimal: 3.14 becomes three point one four. Each digit after the point is named.
- Negative: -7 becomes minus seven.
Pro tips
- Output is always American English. 101 is one hundred one, not one hundred and one.
- Grouping commas are optional: 1234 and 1,234 produce the same words.
- Decimals name each digit after the point. Trailing zeros after the point are dropped.
- The integer part is capped at 15 digits (999 trillion). Split a larger value if you need more.
- Pair with Percentage Calculator or CM to Inches Converter when a workflow mixes numbers and units.
Frequently asked questions
What language are the words in?
Always American English, on every locale of this page. Spanish, Portuguese, French, and German translate the labels and FAQ, but 123 still becomes one hundred twenty-three. That keeps checks, invoices, and English-language forms consistent.
Do you write and like British English?
No. 101 is one hundred one, not one hundred and one. Hyphens are used in compounds such as twenty-one.
Can I convert decimals and negatives?
Yes. Decimals use point plus one word per digit (3.05 → three point zero five). Trailing zeros after the point are dropped. Negatives start with minus.
How large a number can I convert?
The integer part can have at most 15 digits (up to 999 trillion). Grouping commas are stripped first. Scientific notation such as 1e6 is not accepted.
Is my number uploaded?
No. Conversion runs entirely in your browser. Nothing you type is uploaded, logged, or stored.
