About Kilometres per kilogram
The kilometre per kilogram (km/kg) is the standard metric mass-based fuel efficiency unit. Toyota Mirai FCEV: ≈140 km/kg H₂; current-generation hydrogen buses: 8-12 km/kg; LPG cars: 12-17 km/kg; CNG cars: 14-18 km/kg. Aviation: Airbus A320neo ≈0.08 km/kg fuel per seat. 1 km/kg = 1000 m/kg ≈0.621 mi/kg.
About Feet per pound
The foot per pound (ft/lb) equals ≈6.720 × 10⁻⁴ km/kg, the smallest practical mass-efficiency unit. It appears in historical US Army ballistic tables and early solid-propellant rocket motor test sheets where range was in feet and propellant charge in pounds. 1 ft/lb ≈6.720 × 10⁻⁴ km/kg ≈1/3 the size of a metre per pound.
