Beginning a Sentence, Title, Subtitle, or Heading
19.2.1 Beginning a Sentence, Title, Subtitle, or Heading

When a unit of measure follows a number that begins a sentence, it too must be written out, even if the same unit is abbreviated elsewhere in the same sentence. Because this construction can be cumbersome, rewording the sentence may be preferable (see 18.3, Units of Measure, Format, Style, and Punctuation).
