Introduction
When you use numbers in nonscientific writing,
follow these conventions:
- Spell out numbers that can be written in
one or two words. Use figures for longer numbers:
twenty-five
two hundred
248
1,516
- Use figures for dates, addresses, exact
amounts of money, pages or divisions in written works, percentages
using the symbol %, decimals, identification numbers, exact times,
and times of day (with A.M. or P.M.).

- When a number begins a sentence, spell
it out or reword the sentence:
One hundred ten years have passed since
then.
Since then, 110 years have passed.
- Use both figures and words in the same
sentence if necessary for clarity:
The limit here is six 6-inch trout.
He lives at 77 Seventh Avenue.
- Use figures for quantities in scientific
or technical writing. Preferably, use figures for all the numbers
if a paper has many numbers or mixes whole numbers and decimals.
