class UnitFuelEfficiencyOverview
You typically use instances of UnitFuelEfficiency to represent specific quantities of fuel efficiency using the NSMeasurement class.
Fuel Efficiency
Fuel efficiency corresponds to the thermal efficiency of a process that converts the chemical potential energy of a fuel into kinetic energy. Fuel efficiency can be expressed by SI derived units in terms of cubic meters per meter (m3/m), but is more commonly expressed in terms of liters per kilometer (L/km) and miles per gallon (mpg).
The UnitFuelEfficiency class defines its baseUnit() as litersPer100Kilometers, and provides the following units:
Name | Method | Symbol |
|---|---|---|
Liters Per 100 Kilometers | L/100km | |
Miles Per Gallon | mpg | |
Miles Per Imperial Gallon | mpg |
