How to use it
Type a number and its English words appear straight away, ready to copy. Commas, spaces and underscores are ignored, so 1,234,567 works, and you can use decimals (3.14 is “three point one four”) and negatives (“minus five”). Whole numbers also get an ordinal, such as “twenty-first” or “one hundredth”, and a line for writing a cheque: the whole part in words followed by the cents as a fraction, like “One thousand two hundred thirty-four and 56/100”. Numbers up to 21 digits are supported, which goes up to the sextillions.
American and British style
In American English a number such as 123 is “one hundred twenty-three”. In British English it is “one hundred and twenty-three”, with an “and” after the hundreds, and also before the last part of a thousand or a million (“one thousand and five”). Switch the style with the buttons above. The words use the short scale used by both countries today: a billion is a thousand million. Hyphens join the tens and ones from 21 to 99 (“forty-two”).
Questions
Why are decimals read digit by digit? That is how they are normally said aloud: 0.75 is “zero point seven five”. Can I use it for the amount on a cheque? The cheque line is a convenience, so check the wording with your bank’s rules. Does it work for other languages? Only English.
