Frequently Asked Questions
How do I write numbers in words on a check?
For checks, write the dollar amount in words after converting, then add "/100" for cents. For example, $1,250.75 becomes "one thousand two hundred fifty and 75/100 dollars". Always draw a line after the amount to prevent alterations.
What's the difference between US and UK number formats?
The main differences are: (1) UK English uses "and" before tens/units (e.g., one hundred and one), while US often omits it; (2) In the past, UK used "milliard" for 10^9 (now billion in both); (3) Some historical UK formats used different scales (long scale vs short scale).
How are decimal numbers converted?
Decimal numbers are converted as whole number portion plus decimal fraction. For example, 123.45 becomes "one hundred twenty-three and forty-five hundredths". The decimal portion is always converted as a fraction over a power of ten.
What's the largest number this tool can convert?
The tool can convert numbers up to 999 nonillion (999 followed by 30 zeros). Beyond this, the tool will display an error message.
Why isn't my number converting?
Check that: (1) You're using only digits, commas, and a single decimal point; (2) The number isn't too large (max 30 digits); (3) You're not using scientific notation; (4) There are no letters or special characters besides '-' for negative numbers.
