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 Nautical miles per ounce
The nautical mile per ounce (nmi/oz) equals ≈65.33 km/kg, the highest-resolution imperial mass-efficiency unit for light aircraft and UAVs. Micro-UAS with small fuel tanks (few ounces) use nmi/oz to compare range on different fuel blends. A hydrogen-powered small UAV at 140 km/kg ≈2.14 nmi/oz. 1 nmi/oz ≈65.33 km/kg = 16 nmi/lb.
