Frequently Asked Questions
Most style guides (APA, MLA, Chicago) recommend spelling out numbers from one through nine or one through ten. Numbers above that are written as numerals. However, always spell out a number at the start of a sentence, and use numerals for measurements, statistics, and percentages.
This tool supports numbers up to the trillions (999,999,999,999,999). For most academic writing purposes, this is more than sufficient.
Yes. For decimal numbers, the tool converts the integer part normally and then says 'point' followed by the decimal portion. For example, 3.5 becomes 'three point fifty'.
Writing numbers as words improves readability in formal text, avoids ambiguity, and follows the conventions of academic and professional writing. It also prevents sentences from starting with a numeral, which is considered poor style.
