There are different conventions regarding the punctuation of abbreviations. In Australia, contractions (abbreviations from which the middle is omitted, rather than the end, such as DrCwlth) are not usually given full stops.

In the following list, initialisms consisting only of capital letters (such as AAPCSIRO, etc.) are not given full stops, but abbreviations containing lower-case letters (such as Jan.tbsp., etc.) do have full stops (unless they are contractions). However, other conventions may be adopted, such as placing full stops between the letters of an initialism (A.A.P.C.S.I.R.O., etc.), using full stops only for abbreviations which consist entirely of lower-case letters (so Jan, but tbsp., etc.), or abandoning full stops altogether (AAPUWSJantbsp).

Note that symbols, such as cm for centimetreCu for copper, etc., are not generally given full stops, regardless of the case of their letters.
