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.

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.
