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 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.
