About Nautical miles per kilogram
The nautical mile per kilogram (nmi/kg) equals exactly 1.852 km/kg, used in aviation and maritime fuel performance analyses expressed in metric mass units. A large turbofan airliner achieves ≈0.15-0.25 nmi/kg of jet fuel per seat; a high-efficiency glider with a small auxiliary engine around 5-20 nmi/kg. 1 nmi/kg = 1.852 km/kg.
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.
