When using two or more numbers in a single sentence, use all words or all figures. If one number in a sentence is 100 or more, it must be expressed as a figure, all numbers in that sentence that refer to like things must be expressed as figures.

USE FIGURES

1. For cardinal and ordinal numbers 100 or greater or fractional numbers 10 or greater. This rule does not apply when space is a consideration. In these situations, use numerals for numbers 10 or greater.

Examples: There were fourteen of us at the meeting. The correct answer is 14-1/2.

2. For hours of the day, use necessary notation.

Example: 1 p.m. (Note: not 1:00 p.m.); 4:30 a.m.

When used casually or emphasizing the exact moment of time, times of the day should be spelled out.

Examples: Do you know it's after one? It was two o'clock before he went to lunch. If we hurry, we can catch the eight-fifteen train.

3. For dates (omit nd, th, and st: the meeting will be on July 1, not July 1st).

4. For dimensions, distances, degrees of temperature, and percents in scientific use. In non-scientific use, follow normal guidelines.

5. For election results, times in races, scores, proportions, page numbers, chapters, street numbers, and serial numbers.

6. For sums of money (with $ or cents) Examples: $4,480, $24, $3.06, 5 cents. The dollar sign is used on round sums of millions or billions.

Examples: $1 million; $2,350,000

7. When citing even dollar amounts, do not use zeros.

Examples: $5, not $5.00

8. For cumulative grade-point averages. Examples: 3.0, 2.5.

DO NOT USE FIGURES

1. For fractions that stand alone

Examples: one-third, three-fifths

2. At beginnings of sentences. Recast the sentence or spell the number out.

3. When writing rounded figures of 1 million or greater. Use the written word to replace the zeros.

Examples: two million, 18-1/2 billion, five trillion dollars

4. In casual uses, especially within direct quotes

Example: We had a hundred students.
