Do you use this: % symbol, or this: percent (spelled out)? Read this article to understand Dragoman Style, which is mainly based on the AP Style Guide and enriched by Diana Hacker’s, Brian Garner’s and Strunk & White.
1. The word percent is one word. Do not use U.K. spelling, i.e., per cent.
2. Always spell out percent in paragraph content as in 30 percent, 3.5 percent, 66 percent.
3. For percents “less than 1” use zero before the decimal point as in 0.3 percent or 0.03 percent.
4. Use the symbol ONLY in these cases: headlines or headings; and in stand-alone short statements or phrases on websites and in annual reports, research reports, etc.
Headlines or Headings
