Number to Words Calculator

This calculator spells a whole number out in plain English, the way you would write it on a cheque, in a legal contract, or when teaching a child how place value works. Type any whole number into the box, including a negative number if needed, and the calculator instantly converts it into words, correctly grouping the digits into hundreds, thousands, millions, billions, trillions and up to the quadrillions using the short scale standard in New Zealand and most English-speaking countries. Alongside the words, you get the number of digits in your figure and the same value shown with comma separators, so you can quickly check you have typed the right number before copying the words across. Compound tens such as thirty-four are joined with a hyphen, matching standard written English, and a negative number is prefixed with the word negative rather than a minus sign. The calculator accepts any whole number up to 999,999,999,999,999, anything larger is outside its range. Try the default value of 1234 to see it become one thousand two hundred thirty-four, or enter 1000000 to see one million, then swap in your own figure for a cheque amount, a contract sum, an invoice total or a maths lesson on how digits translate into spoken and written language.
