i'm curious as to why we writers of American English
use a "." after Mr., Ms., and Mrs., whereas
the British do not. are there other examples of
British English abbreviations that do not employ the period?

apologies to those UK'ers who might object to the
redundancy of `British English' :-)

I don't think this is specific to those abbreviations; it appears to be
part of a common style of omitting full stops (all right, periods :-))
from abbreviations altogether. For example, "P O Box", "Jane E Smith, BSc".

I wonder if the origin of this style has anything to do with the use of
SI units of measurement in Britain (you know--metres and kilograms), where
the official recommendation is to write "cm", "kg" and so on _without_
full stops?

The BrE rule is simple: an abbreviation gets an abbreviation point
if and only if the last letter of the abbreviation is not the last
letter of the word abbreviated.

"Mr" abbreviates "Mister"; the last letter of both is "r"; no point.
"Bro." abbreviates "Brother"; the last letters disagree; point needed.

The BrE convention gives you a jot more information.

They'll be easy to find; in English, the rule is that if an abbreviation
ends with a letter from the original word (i.e. the removed letters are from
the middle of the word) then don't terminate with a ".". Therefore Dr will
not have a point, but Doc. will...

Neither the full spelling "centimeter" nor "centimetre" of the abbreviation
"cm" seems to be consistent with this rule. Similarly, "kilogram" and
"kilogramme" don't end with a 'g' as "kg" does. Can anyone reconcile this
with the above quotes?

Shouldn't that be "BrE."? :')

"cm" seems to be consistent with this rule. Similarly, "kilogram" and
"kilogramme" don't end with a 'g' as "kg" does. Can anyone reconcile this

The SI rules are not the British rules, but a different set al-
together. In the SI rules, the standard abbreviations have no
periods.

Michelle asks:

I was taught in India that certain abbreviations, like Dr, Mr, Mrs, are
so commonly used that they had reached the status of full-fledged words
and did not require a period at the end.

Today, periods and commas are far less used.
