About Metres per kilogram
The metre per kilogram (m/kg) is the SI coherent derived unit of mass-based fuel efficiency. It is used in combustion research, rocket propellant comparative testing, and laboratory fuel-cell efficiency benchmarking. A car at 15 km/kg petrol = 15 000 m/kg; a hydrogen fuel cell bus at 120 km/kg H₂ = 120 000 m/kg. 1 m/kg = 1e⁻³ km/kg = 1/1000 km/kg.
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.
