Frequently asked questions
What numbers are supported?
Integers, decimals (e.g. 3.14 → three point one four), negative numbers, and currency amounts up to 999 trillion. You can use commas as thousands separators and a leading $ symbol.
What is the currency mode?
Currency mode splits the number at the decimal point and reads it as dollars and cents — e.g. $19.99 becomes "nineteen dollars and ninety-nine cents". Great for writing checks and invoices.
Why does this tool use a hyphen in twenty-one?
Standard English grammar requires a hyphen between tens and ones for numbers 21–99 (e.g. twenty-one, forty-two). This follows AP, Chicago, and most style guides.
What does the "and" option do?
British English commonly inserts "and" after the hundreds: "one hundred and twenty-three". American English usually omits it. Toggle the checkbox to switch styles.
