bbl

Etymology 1
Often thought to be modified from bl for barrel (b⸺l), reflecting a way of abbreviating that was used especially in previous centuries (compare for ), wherein a doubled letter indicated plural count, as also with =page but =pages and =line but =lines; this method was used not only in English but also in scholarly New Latin and other modern languages heavily affected thereby, such as with Spanish  According to this idea, addition of the suffix, as sometimes seen (e.g., 5 bbls or 5 bbls.), would seem to have come from writers who left the unit abbreviation itself unanalyzed (unparsed), thus adding a venially redundant marker of plural, somewhat like with MPGs for miles per gallon.
