Rule #2: When abbreviating academic degrees and professional designations, use a period between each letter or element in the abbreviation. No internal spaces are necessary.
For very common abbreviations, leave out the periods, as in rpm and mph. When an abbreviation with a period ends a sentence, that period will suffice to end the sentence: He lives in Washington, D.C. Suffixes for people's names require periods: Joe Smith Jr. lives in Erie.here is a space between the number and the abbreviation. Notice that we do not put an s after such abbreviations even when the plural is indicated. Also, we do not use a period with such abbreviations except for in. when it might be confused with the preposition in.
