25.0 mpg = 10.6 km/L

Convert miles to kilometres:

We could use the conversion factor 1 mi = 1.609 km. Let’s work instead from numbers we know.

#25.0 mi × (5280 ft)/(1 mi) × (12 in )/(1 ft) × (2.54 cm)/(1 in) × (1 m)/(100 cm) × (1 km)/(1000 m)# = 40.2 km

(Sorry. This editor converts "in" for "inches" into the math symbol #in#.)

Convert gallons to litres:

1 gal = 3.785 L

#(25.0 mi)/(1 gal) = (40.2 km)/(3.785 L)# = 10.6 km/L
