Common fuel consumption conversion mistakes

• US and UK mpg use different gallons: the imperial gallon (4.546 L) is 20% larger than the US gallon (3.785 L). The same car therefore scores about 20% higher in UK figures, 40 mpg UK ≈ 33 mpg US. Check which gallon a source means.
• Mpg is inverted relative to consumption, so improvements are not linear: going from 10 to 20 mpg halves fuel use, while 40 to 50 mpg cuts it by only a fifth. Convert to l/100 km when comparing savings, that scale is proportional to actual fuel burned.
