Frequently Asked Questions
- When should I spell out numbers in APA style?
- In APA 7th edition, spell out numbers zero through nine and use numerals for 10 and above. Exceptions include numbers that begin a sentence (always spell out), numbers in an abstract or graphical display (always use numerals), and commonly accepted usages like "Grade 4" or "5-point scale".
- How does this number to words converter handle large numbers?
- The converter handles numbers up to the trillions, including decimals and negative numbers. For example, 1,234,567 becomes "one million two hundred thirty-four thousand five hundred sixty-seven". Decimal portions are converted digit by digit after "point".
- What is the difference between APA, Chicago, and AP number rules?
- APA spells out numbers zero through nine and uses numerals for 10+. Chicago style spells out numbers zero through one hundred and round multiples. AP style spells out numbers one through nine and uses numerals for 10 and above, similar to APA but starting from one.
- Should I spell out numbers at the beginning of a sentence?
- Yes. All major style guides (APA, MLA, Chicago, AP) require you to spell out any number that begins a sentence. If the number is very large and awkward to spell out, rephrase the sentence so the number does not come first.
