Two ways to group a large number
The international system groups digits in threes. Each step of a thousand gets a new name: thousand, million, billion, trillion. A billion is a thousand million (10⁹) in modern English. Britain once used a “long scale” in which a billion meant a million million, but the UK government adopted the short scale in 1974, and that is what this tool uses.
The South Asian system, used in Pakistan, India, Bangladesh and Nepal, groups the first three digits and then pairs of two. One lakh is 100,000 and one crore is 100 lakh, or 10,000,000. The commas move to match: 1,250,000 is written 12,50,000 and read as twelve lakh fifty thousand. Above a crore, many writers simply keep counting in crores (“one lakh crore”), while others use the traditional names arab (100 crore), kharab (100 arab), neel, padma and shankh. Both are available here.
| Value | International | South Asian |
|---|---|---|
| 100,000 | one hundred thousand | one lakh |
| 1,000,000 | one million | ten lakh |
| 10,000,000 | ten million | one crore |
| 1,000,000,000 | one billion | one hundred crore (one arab) |
| 1,000,000,000,000 | one trillion | one lakh crore |
Writing amounts on cheques
Banks ask for the amount in words because words are much harder to alter than digits. A few conventions make the line tamper-proof:
- End the line with “only” so nothing can be added afterward, and draw a line through any space that is left.
- In the United States, checks usually show the cents as a fraction: “One hundred twenty-three and 45/100 dollars”.
- In Pakistan and India, the currency often comes first: “Rupees one lakh twenty thousand only”. Indian usage writes paise; Pakistani usage writes paisa.
- Many banks prefer Title Case or capitals for legibility. Use whatever your bank’s cheque book shows.
Rules for spelling numbers in English
Numbers from twenty-one to ninety-nine take a hyphen. American English leaves out “and” (“one hundred five”), while British English includes it (“one hundred and five”); tick the option if you need the British form. Decimals are read digit by digit after the word “point”, so 3.14 becomes “three point one four”. In currency mode the amount is rounded to two decimal places, the way money is written.
Worked examples
1,250,000 is “one million two hundred fifty thousand” internationally and “twelve lakh fifty thousand” in the South Asian system.
7,045.10 dollars becomes “Seven thousand forty-five dollars and ten cents only”.
15,00,000.50 rupees becomes “Rupees fifteen lakh and fifty paisa only” with the currency-first option.
Mistakes to avoid
Do not mix systems in one document: “1.5 million” and “15 lakh” are the same amount, but switching between them confuses readers. Check that the words and the figures on a cheque match exactly, since banks can refuse a cheque when they differ. For invoices that need amounts in words, the Invoice Generator is a good companion, and the Currency Converter helps when the amount starts in another currency.
