How this system works
Efficiency (distance per volume) and consumption (volume per distance) are reciprocals. US mpg uses the 231-cubic-inch gallon; UK mpg uses the imperial gallon, so the same car reads about 20% higher in UK miles per gallon. Litres per 100 km is the SI-ish consumption figure used across most of the world.
Base unit: metre per cubic metre. Mile per US gallon is US customary; Litre per 100 kilometres is Metric.
