Number to Words Converter

Writing an amount in words is a legal requirement on cheques, common on invoices and contracts, and standard in legal documents — because words are far harder to alter than digits. It is also where two different worlds collide: the international numbering system groups digits in threes (million, billion), while the Indian system groups the first three and then pairs (thousand, lakh, crore). 1,250,000 is "one million two hundred fifty thousand" in one system and "twelve lakh fifty thousand" in the other — same number, different language.

This converter speaks both, with a one-click switch. It handles numbers up to 15 digits, accepts commas in either grouping style, and reads decimals digit by digit in plain mode. The feature built specifically for real paperwork is the currency mode: switch it on, pick Rupees, Dollars, Euros or Pounds, and the output becomes cheque-ready — "Rupees Twelve Lakh Fifty Thousand and Twenty-Five Paise Only", capitalized, with the closing "Only" that banking convention expects because it prevents anyone appending extra words.

Everyday uses: filling cheques without second-guessing, invoice totals in words, legal drafting, rent agreements, and teaching the lakh–crore versus million–billion correspondence, which trips up even professionals moving between the two systems.
