This number to words converter spells a whole number out in English: 1048576 becomes "One million forty-eight thousand five hundred seventy-six". It uses the short scale (thousand, million, billion, trillion, quadrillion) and handles zero and negative numbers. Commas in the input are ignored. The limit is 9,007,199,254,740,991, the largest whole number JavaScript can store exactly; anything bigger gets an error rather than a wrong answer.

Short scale vs long scale
In the short scale each new name is 1,000 times the last, so a billion is 1,000,000,000. That's the convention in American English, and in British English since the 1970s. The long scale, still used in much of continental Europe, makes a billion a million million. One more style note: the tool doesn't add "and", so 105 comes out as "one hundred five". That's the usual American form; British writers often add the "and" by hand.
