When to Write Numbers as Words
AP Style (used by journalists): spell out one through nine, use numerals for 10 and above. Exception: always use numerals for ages, percentages, and statistics.
Chicago Manual of Style (books and academic writing): spell out one through one hundred. Use numerals for 101 and above. Always spell out numbers that begin a sentence.
APA Style (psychology and social sciences): spell out numbers below 10, use numerals for 10 and above. More exceptions for specific contexts.
Legal writing: typically writes numbers both ways for clarity — "the party shall pay forty-two dollars ($42)" — preventing any ambiguity about the intended amount.
Numbers to Words for Checks
Writing a check requires both the numeral amount (in the box) and the written amount (on the line). The written line must spell out dollars completely: for a $1,250.75 check, write "One thousand two hundred fifty dollars and 75/100." Use this generator to verify the correct spelling of any check amount before signing. An incorrectly written amount on a check can be disputed, rejected, or exploited.
Numbers to Words in Different Languages
This generator converts to English. The pattern of English number words (units, teens, tens, hundreds, thousands) differs from other languages — German compounds numbers differently, French uses a vigesimal system for numbers 70-99, and many languages lack separate words for "billion" distinct from "thousand million." For English content, this generator covers all standard cases up to millions.
