How to write a number in words

Type a number the way you write it in Vietnam or in English: 1.250.000 and 1,250,000 both work, and 12,5 or 12.5 is a decimal. The Vietnamese words, the English words and the money line appear together, in your browser.

  1. Type the number

    “1.250.000”, “1250000” or “12,5”. A minus sign reads “âm”.

  2. Check the words

    Vietnamese follows the rules banks use: mười and mươi, một and mốt, năm and lăm, bốn and tư, linh and lẻ.

  3. Copy

    Press Copy beside the words you need. The money line can end with “chẵn” or without it.

How is a Vietnamese amount written in words?

Type the amount, then copy the money line: 1.250.000 becomes “Một triệu hai trăm năm mươi nghìn đồng chẵn”, or without “chẵn” when you turn that off. A decimal part is read with “phẩy”.

Does it read 21, 15 and 24 correctly?

Yes. 21 is “hai mươi mốt”, 15 is “mười lăm”, 25 is “hai mươi lăm”, 24 is “hai mươi tư” (turn it off for “bốn”), and 101 is “một trăm linh một”.

What about zeros inside a large number?

A group of three zeros is skipped. A group that is not first and starts with zero says “không trăm”: 1.000.005 is “một triệu không trăm linh năm”.

Is my number uploaded?

No. The conversion runs in your browser; the number is not sent anywhere.

Can it read an invoice amount?

Yes, up to 21 digits. Large groups use nghìn, triệu, tỷ, nghìn tỷ and triệu tỷ, which is what Vietnamese invoices use.
