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.
About Miles per ounce
The mile per ounce (mi/oz) equals ≈56.78 km/kg, used for small general aviation aircraft and large model aircraft where fuel loads are a few ounces. A 100 cc glow-engine aircraft consuming 1 oz per mile of flight = 1 mi/oz; small RC turbine jets achieve 0.5-3 mi/oz. Also used in US drag-racing fuel consumption records. 1 mi/oz ≈56.78 km/kg = 16 mi/lb.
