About Miles per US Gallon

Miles per US gallon (mpg(US)) is the US and Canadian standard, displayed on every EPA Monroney sticker and used in CAFE regulations. The US gallon = 3.785411784 L; 1 mile = 1.609344 km. 2026 CAFE passenger car standard: ~49 mpg. Toyota Prius Prime: 52 mpg; Tesla Model 3: 132 MPGe. Historical: Ford Model T 21-25 mpg; 1973 US full-size cars 10-15 mpg. NASCAR at race speed: 4-5 mpg; Class 8 semi: 5-8 mpg. L/100km = 235.21458/mpg(US): 30 mpg = 7.84 L/100km; 50 mpg = 4.71 L/100km.

About Microliters per Kilometer

A microliter per kilometer (µL/km) equals 10⁻⁴ L/100km - a unit reserved for laboratory engine testing and fuel cell research. A car consuming 7 L/100km corresponds to 70,000 µL/km, illustrating why µL/km is used only for scientific contexts: GDI injectors deliver 10-50 µL per injection event; engine oil blowby consumption is measured in 50-500 µL/km; hydrogen fuel cell prototype comparisons use µL-equivalent/km. Single-cylinder research engines log fuel use in µL/shot to map combustion efficiency across load sweeps. 1 µL/km = 0.0001 L/100km.
