    Quoted from http://grammar.ccc.commnet.edu/grammar/abbreviatio...

    Spacing and Periods

    Abbreviations of units of measure are written without periods (with the exception of "in" when it could be confused with the preposition). We use periods for most lower-case abbreviations such as e.g. and i.e. and c.o.d. 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. In formal text it is not a good idea to abbreviate military titles — Lieutenant Colonel Chester Piascyk — but in informal text Lt. Col. Chester Piascyk would be acceptable. (Note the space after "Lt.") Academic degrees can be written with periods or not, but don't insert spaces — Ph.D. or PhD, M.B.A. or MBA — within the degree.

  • I get up at 6 a.m.
