You typically use instances of
NSUnit to represent specific quantities of fuel efficiency using the
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).
NSUnit class defines its base unit as
liters, and provides the following units:
