```IIRC, there are also some (minor) differences in the heat & energy units,
but these might be derivative differences based on the volume differences.

Let's not even get started on that pound-mass and kilogram-force vs.
pound-force and kilogram-mass debate.

Well, actually the ENGLISH or IMPERIAL units (as far as my knowledge about
the subjec goes) are  basically one & the same thing. The US CUSTOMARY is
derived from the ENGLISH/IMPERIAL units. By far this is (as mentioned by
your goodself) the only difference that i have encountered between these two

sisters. That is 1 US GALLON = 0.883 IMP. GALLON  OR
1 IMP. GALLON =1.2 US GALLON. I would be interested to learn about other
venues of differences (if any ?) as well. Regards,
