- Ages

- Degrees of temperature
- Dimensions
- House numerals

Time in AP Style
Always remember that your job is to simplify the information, not complicate it. Follow these quick tips for time in AP style:
- Lowercase a.m. and p.m. and use periods.
- Do not use :00 after an on-the-hour time. Simply use the numeral.
- Avoid redundancies like 9 p.m. Tuesday night.
- Use noon or midnight for 12:00, but only use the word, not the redundant 12 noon or 12 midnight.
Use Punctuation and Capitalization Sparingly
Unlike other types of writing, Associated Press style uses the least amount of punctuation and capitalization necessary to convey the intended message. AP style’s goal is clear, concise writing, and punctuation’s goal is to guide readers, not confuse readers.
Capitalize proper nouns and other nouns occasionally when they are used with a proper noun. Do not use the serial comma (the final comma before the conjunction) in a series.
Avoid Alphabet Soup
While acronyms and abbreviations are preferred after first reference for some words and organizations, readers should immediately understand the acronym or abbreviation. Do not use multiple acronyms or abbreviations in a sentence unless their meaning is transparent. Don’t make readers spoon through alphabet soup to understand your intention.
Do not use periods for most acronyms, but do use periods for two-letter acronyms: FDA for Food and Drug Administration or U.S. for United States. If the acronym spells an unrelated word, use periods between letters to avoid confusion.
If these quick tips haven't already made this clear, here's one more reminder: keep it simple, avoid redundancies and use minimal capitalization and punctuation.
