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 Metres per pound
The metre per pound (m/lb) equals ≈2.205 × 10⁻³ km/kg, a transitional unit bridging SI metres with imperial pound mass. It appears in some international academic fuel cell papers and comparative combustion analysis where authors mix SI distance with US fuel weight measurements. 1 m/lb ≈2.205 × 10⁻³ km/kg ≈1.094 yd/lb.
