imp mpg to L/100 km context and checks

Best use
Use fuel-efficiency conversions when comparing vehicle economy across mpg, km/l, L/100 km, or similar labels.
Common mistake
Some fuel units are inverse: better efficiency can mean a higher value in mpg but a lower value in L/100 km.
Precision note
Do not average inverse fuel-efficiency units directly; convert trips or fuel amounts consistently before comparing.

Example check: 5 imp mpg converts to 56.4961873 L/100 km. Use this known value to sanity-check a spreadsheet, homework solution, spec sheet, or manual calculation.
