About Kilometres per gram

The kilometre per gram (km/g) equals 1000 km/kg, the unit for ultra-efficient propulsion systems and hydrogen fuel cell vehicles. A Toyota Mirai at 140 km/kg H₂ = 0.14 km/g; hypothetical rocket-propellant comparison studies use km/g to express chemical energy density. A solid-propellant gas generator releasing 1 km of equivalent travel per gram of propellant represents extreme efficiency. 1 km/g = 1000 km/kg.

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.
