Rules for Using Abbreviations & Acronyms

Acronyms should be in capital letters without a period after each letter (ATM, CEO).

To form the plural of abbreviations and acronyms, add an “s.” Do not include an apostrophe (ATMs, CEOs).

When introducing abbreviations or acronyms that readers may not be familiar with, write out the entire term the first time with the shortened version in parenthesis.

Abbreviate all measurements as lowercase terms without periods (ft, in, oz).
