The important thing to remember is that a litre is a measure of volume and
/never/ anything else and a kg is always weight. It's less confusing than
ounces which can be either.
You can measure water, custard powder, and propane all in litres but it
would be the volume of such you would be talking about.
Equally you measure all the above in kg and it would be the weights you
would be talking about.
(Of course they still measure oil in "barrels" which is bizzare)
I'm old enough to remember when the uk was exclusively imperial and for
many things think in imperial. Metric was the measurement for science so
in the science lab I measured things in gramms but weighed my potatoes (so
to speak) in lb!
I use litres for measuring liquids for etching but buy my beer in pints!
Only thing confuses me now is loudspeaker cabinet volumes are now measured
in litres instead of cubic feet. I can only visualise the size of a
loudspeaker by converting litres to gallons, gallons to cubic feet and
then saying to myself "Oh that box would be about 18inches 9inches by
2foot"
