Automotive
Automotive tools help with trip cost and fuel economy questions.
Units are spelled out on each page (US liquid gallon, US vs Imperial MPG) so results are not mixed across regional definitions. L/100 km and MPG are inverses of each other, not two spellings of the same number — converting 30 US MPG is not the same as converting 30 UK MPG.
A fuel-cost estimate is distance × consumption × price. Road-trip pages add those pieces; they do not invent tolls or hotel nights.
