Which Arabic dialect does this use?

It uses Modern Standard Arabic (الفصحى) cardinal numbers in the common masculine form, which is what is used in writing and formal documents across the Arab world.

Does it handle the special forms like مئتان and ألفان?

Yes — it uses the dual forms مئتان (200) and ألفان (2000), the plural آلاف/ملايين/مليارات for 3-10, and the connector و between groups.

How large a number can I convert?

Up to 12 digits, which covers values into the billions (مليار). Larger groups are spelled with their plural scale words.

How are the scale words made plural?

Arabic uses different forms by count: ألف for one thousand, ألفان for two thousand, and the plural آلاف for 3-10 thousands. The same pattern applies to مليون/ملايين and مليار/مليارات.

Does it read out decimals?

This tool spells whole numbers. For monetary amounts, convert the whole part and add the fractional currency unit (such as قرش or فلس) yourself.

Is my number sent anywhere?

No — the conversion runs entirely in your browser with no network requests.

Number to Words in Arabic

This tool spells any whole number into Modern Standard Arabic (الفصحى) words — the form used in writing, contracts and formal documents across the Arab world. It is useful for invoices, cheques and teaching, and runs entirely in your browser.

How it works

The number is split into groups of three digits (units, thousands, millions, billions). Each group of up to three is spelled with the standard hundreds, tens and units words, and then joined to its scale word — ألف (thousand), مليون (million), مليار (billion). Arabic chooses the scale word’s form by count: the singular for one, the dual (ألفان, مليونان) for two, and the plural (آلاف, ملايين, مليارات) for 3-10. Groups are joined with the connector و, and the output reads right-to-left.

Example

The number 1234 breaks into 1 thousand and 234:

Part	Arabic
1000	ألف
200	مئتان
34	أربعة وثلاثون

Joined with و, the result is ألف ومئتان وأربعة وثلاثون.
