SUMMARY
***
STEPS TO REPRODUCE
1.  Type in 1 gallon or other amount in krunner
2. 
3. 

OBSERVED RESULT
Result listed is 3.7854099999999997 l - which is correct only for US Gallons, not imperial.

EXPECTED RESULT
Any of the below would be a more helpful result:
1) Output should make it clear that it has done the conversion from a US gallon, not imperial - or supply a separate result for each of the conversions. It could also warn that US / Imperial gallons are different.
2) Program should allow user to specify e.g. 1 US Gallon, 1 Imperial Gallon, etc and then give the correct result for that. OR it should use localisation settings to guess at what the user means.
