Frequently asked questions
How do you write 1234 in words?
One thousand two hundred thirty-four. American convention omits 'and' before the tens (British style would say 'one thousand two hundred and thirty-four') — both are understood.
How do you write amounts on a check?
Write the cents as a fraction: 'One thousand two hundred thirty-four and 56/100 dollars'. The word form controls the legal amount, which is why it must match the digits exactly.
What is the biggest number this converts?
Up to 999,999,999,999,999 — the trillions scale. Beyond that, scientific notation is the clearer choice for everyone involved.
Why do hyphens appear in some numbers?
Compound numbers from twenty-one to ninety-nine take a hyphen (forty-two, seventy-five). It is standard English orthography, and the converter applies it automatically.
