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 Yards per pound
The yard per pound (yd/lb) equals ≈2.016 × 10⁻³ km/kg, found in old British and US military propellant efficiency tables and pre-metric naval gunnery manuals. Range achieved per pound of cordite or smokeless powder was stated in yards. 1 yd/lb ≈2.016 × 10⁻³ km/kg ≈ 3 ft/lb.
