Miles per gallon gasoline equivalent will go per amount of fuel (units of MPGe). Fuel consumption is the reciprocal of fuel economy, and measures the fuel used to drive a fixed distance (units of Gal/100 miles or kW-h/100 miles). The unit of Gal/100 miles is accurately described as fuel consumption in some EPA brochures, but this unit appears in the fuel economy section of the Monroney label (which doesn't use the term fuel consumption). The miles per gallon gasoline equivalent is based on the energy content of gasoline. The energy obtainable from burning one US gallon of gasoline is 115,000 BTU, 33.70 kWh, or 121.3
