Why write numbers in words?
Writing amounts in words is standard on checks, invoices, contracts and receipts because it prevents tampering: it's easy to change “1000” into “7000”, but much harder to alter “one thousand dollars”. This tool spells out any number instantly in English and in grammatically correct Arabic (known as tafqeet), including currencies and fractional units.
How to use it
- Type a number or amount. You can use Western (123) or Arabic-Indic (١٢٣) digits, with decimals after a point.
- Choose a currency — US dollar, euro, Moroccan or UAE dirham, Saudi riyal, Egyptian pound, dinars — or “No currency” for the plain number.
- Enable “Check format” to append “only” (and “فقط … لا غير” in Arabic).
- Copy the English or Arabic result with one click.
Rules for writing amounts on checks
- Start writing at the far left of the line so nothing can be added before the words.
- Hyphenate compound numbers from twenty-one to ninety-nine (forty-five).
- Write cents either in words (“and fifty cents”) or as a fraction (“and 50/100”).
- Finish with “only” and draw a line through any remaining space.
- Make sure the amount in words matches the figure box exactly — banks treat the words as authoritative if they differ.

| 2,000,000 | two million dollars |
About Arabic number words
Arabic number words follow detailed grammar rules: one and two agree with the counted noun, three to ten take the opposite gender with a plural noun, eleven to ninety-nine take a singular accusative noun, and hundreds and thousands take a singular genitive noun. The tool applies all of these automatically, which makes it handy for anyone preparing bilingual invoices for Arabic-speaking clients.
Frequently Asked Questions
How do I write a check amount in words?
Enter the amount, choose the currency, enable “Check format” and copy the result. Start writing at the left edge of the line.
Are cents and other sub-units supported?
Yes. Type decimals like 99.50 and the sub-unit (cents, halalas, fils, centimes…) is written automatically.
What is the largest number supported?
Up to 15 digits — hundreds of trillions — more than enough for any financial use.
Should I use “and” in English amounts?
Both styles are accepted. British English typically says “two hundred and fifty”; on US checks “and” is often reserved for cents.
Is the Arabic grammatically correct?
Yes. The tool applies Arabic number–noun agreement rules for gender, number and case.
