About Nautical miles per pound
The nautical mile per pound (nmi/lb) equals ≈4.083 km/kg, the standard fuel efficiency unit in US and NATO aviation engineering. Range planning for US Navy, USAF, and FAA-certified aircraft uses nmi/lb or gallons/nmi; ICAO fuel planning worksheets include nmi/lb columns. Typical values: commercial turbofan 0.10-0.25 nmi/lb; turboprop commuter 0.08-0.15 nmi/lb. 1 nmi/lb ≈4.083 km/kg.
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.
