You must be using imperial firkins (at least that's the term we use in
the U.S.). In an idle moment I decided to check this out using the
UNIX 'units' program and was initially confused:
% units
you have: firkins / fortnight
you want: liter / day
* 2.433479e+00
/ 4.109343e-01
Then I was inspired, recalling the difference between imperial gallons
and gallons
you have: imperial firkins / fortnight
you want: liter / day
* 2.922487e+00
/ 3.421744e-01
and managed to get your conversion factor of 2.9.
The firkins / fortnight unit reminded me of a unit of velocity someone
once told me he especially liked: furlongs / fortnight.
you have: furlong / fortnight
you want: meter / second
* 1.663095e-04
/ 6.012885e+03
you have: furlong / fortnight
you want: meter / day
* 1.436914e+01
/ 6.959357e-02
