What is the largest number that can be converted?

Up to 999,999,999,999,999 (nearly one quadrillion). Larger numbers require scientific notation.

What is an ordinal number?

Ordinals express position or rank: first, second, third, fourth... instead of cardinal numbers: one, two, three, four. Common in competition rankings and legal text.

How are currency amounts converted?

Decimal amounts are split at the decimal point: dollars become the whole part, and cents are the remaining two decimal digits (e.g., 42.75 → 'forty-two dollars and seventy-five cents').

Why do some style guides capitalize numbers in legal documents?

Legal and formal writing often requires spelling out numbers to prevent tampering (e.g., 'one hundred dollars' is harder to alter than '$100'). This tool outputs lowercase — capitalize as your style guide requires.
