How to use the converter
- Type the number. Commas, spaces and a decimal point are all fine — 1,234,567.89, 1234567.89 and the Indian 12,34,567 are read the same way. A minus sign in front makes it negative. The converter handles everything up to 999,999,999,999,999, just under a quadrillion.
- Choose how to write it. Words spells the number out (and reads any decimals digit by digit). Check amount splits the number into dollars and cents — or rupees and paise, pounds and pence, euros and cents — and adds the line you write on a check. Ordinal gives the position form: first, second, twenty-first.
- Pick the letter case and press Copy next to the version you want. US style comes first; when British English or Indian numbering would read differently, those versions appear underneath.
The rules for writing numbers in words
English names numbers in groups of three digits. Each group is read as a number from one to 999 and followed by its scale word: thousand, million, billion, trillion. So 7,045,300 is seven million forty-five thousand three hundred. A few details trip people up:
- Hyphenate 21 to 99. Compound numbers from twenty-one to ninety-nine take a hyphen — twenty-one, forty-five, ninety-nine — wherever they appear: three hundred twenty-one thousand. Round tens (twenty, forty) and the words hundred, thousand and million never do.
- No plural on scale words. It is two hundred, five thousand and three million, not “thousands” or “millions”, when an exact number comes before them.
- “And” in American English. US style guides keep and for the decimal point or the cents: 101 is one hundred one, and $101.50 is one hundred one dollars and fifty cents. Saying “one hundred and one” is common in speech, but on a US check the extra “and” can blur where the dollars end.
- Spelling. Forty has no u (four, fourteen, but forty), and ninety keeps the e of nine. Eighth has only one t, and twelfth keeps the f.
- Decimals. Read the digits after the point one at a time: 3.14 is three point one four, and 0.05 is zero point zero five.
How to write a check amount in words
A US check asks for the amount twice: in figures in the box, and in words on the line that ends with “Dollars”. Write the whole dollars in words, then and, then the cents as a fraction of 100. For $1,250.75 that is:
One thousand two hundred fifty and 75/100
- Start at the far left of the line and draw a line through the empty space after the fraction, so nothing can be added.
- Write 00/100 for a round amount (Fifty and 00/100), so no one can add cents later.
- For less than a dollar, write Zero and 50/100.
- The words count more than the figures. Under the Uniform Commercial Code (§ 3-114), when the two disagree, words prevail over numbers — another reason to take the words from a converter rather than from memory.
British English: one hundred and one
In the UK, Ireland, Australia and most other English-speaking countries, and goes before the last two digits of each group: one hundred and one, three hundred and forty-five thousand six hundred and seventy-eight. It also links thousands or millions to a final number below 100: one thousand and five, two million and fifty. For pounds, the converter writes the British cheque form — One hundred and twenty pounds only, or …pounds and 5p when there are pence.
Indian numbering: lakh and crore
India, Pakistan, Bangladesh and Nepal group digits differently after the first thousand: in pairs instead of threes. One lakh is 1,00,000 (one hundred thousand) and one crore is 1,00,00,000 (ten million).
| Figure | Indian words | International words |
|---|---|---|
| 1,00,000 | one lakh | one hundred thousand |
| 10,00,000 | ten lakh | one million |
| 1,00,00,000 | one crore | ten million |
| 1,23,45,678 | one crore twenty-three lakh forty-five thousand six hundred seventy-eight | twelve million three hundred forty-five thousand six hundred seventy-eight |
| 1,00,00,00,000 | one hundred crore | one billion |
In formal writing, lakh and crore usually stay singular after a number: twenty lakh rather than “twenty lakhs”. On a cheque, the amount usually opens with Rupees and closes with only: Rupees one lakh twenty-five thousand only, or Rupees … and fifty paise only when there are paise. Choose Indian rupees as the currency to get both forms.
Ordinal numbers
Ordinals give a position — first, second, third — and change only the last word of the number: 121st is one hundred twenty-first, and 1,000th is one thousandth. Most simply add -th (fourth, sixth, hundredth). The exceptions are first, second, third, fifth, eighth, ninth and twelfth, and tens ending in y change it to ie: twentieth, fiftieth. In figures, 1, 2 and 3 take st, nd and rd (21st, 32nd, 43rd), except 11th, 12th and 13th, which always take th.
When to spell numbers out
Most US style guides spell out numbers in running text below a cutoff — AP style up to nine, Chicago up to one hundred — and always at the start of a sentence. Legal documents, contracts and invoices often give both, as in “ten thousand dollars ($10,000)”, so a typo in one can be caught by the other.

Frequently asked questions
How do you write 1,000,000 in words?
One million. Two million is two million — no “s” after an exact number — and 1,500,000 is one million five hundred thousand. In Indian numbering the same 10,00,000 is ten lakh.
Should I write “and” in numbers like 101?
In American English, no: one hundred one, keeping “and” for the cents or the decimal point. British, Irish and Australian English put “and” before the last two digits: one hundred and one. Both are correct in their own region.
How do I write cents on a check?
After the dollars in words, write “and” and the cents as a fraction of 100: $82.40 becomes Eighty-two and 40/100. For a whole-dollar amount, write and 00/100 so no cents can be added.
Is it forty or fourty?
Forty. Four and fourteen keep the u, but forty drops it. Ninety, on the other hand, keeps the e of nine.
How do you write 1 lakh in words?
One lakh, which is 1,00,000 — one hundred thousand in the international system. Ten lakh is one million, and one crore (1,00,00,000) is ten million.
Do you hyphenate numbers like twenty-one?
Yes. Every compound number from twenty-one to ninety-nine is hyphenated, even inside a larger number: two thousand four hundred fifty-six. Hundred, thousand and million are never joined with hyphens.
