About Kilometres per pound
The kilometre per pound (km/lb) equals ≈2.205 km/kg, common in US-to-metric cross-border transport analysis and fuel research papers where distances are in km but fuel invoices are weighed in pounds. A car burning 6 kg/100 km petrol gets ≈16.7 km/kg = 7.57 km/lb. 1 km/lb = 1/0.45359237 km/kg ≈2.205 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.
