About Miles per pound

The mile per pound (mi/lb) equals ≈3.548 km/kg, the traditional US aviation mass-efficiency unit. Cessna 172 on avgas: ≈0.28-0.32 mi/lb; Piper Cherokee: ≈0.30-0.35 mi/lb; Boeing 737 MAX per seat: ≈0.10-0.15 mi/lb. US military aircraft fuel efficiency analyses and early NASA propellant studies used mi/lb. 1 mi/lb ≈3.548 km/kg = 1.609344/0.45359237 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.
