About Pounds per hour
The pound per hour (lb/h) equals 0.45359237/3600 ≈ 1.260×10⁻⁴ kg/s, the dominant unit in US process engineering and steam-boiler rating. Packaged steam boilers are rated in lb/h of steam output (typical range 100-2 000 lb/h); HVAC cooling-coil latent loads are calculated in lb/h of moisture; flue-gas emission inventories are reported in lb/h per stack. 1 lb/h ≈ 1.260×10⁻⁴ kg/s.
About Kilograms per second
The kilogram per second (kg/s) is the SI coherent derived unit of mass flow rate relevant across all branches of engineering. Jet turbofan engines pass 100-800 kg/s of air through the core and bypass duct combined; drinking-water intake pipelines for a city of one million people sustain flow rates of 1 000-4 000 kg/s. It is the reference unit in the continuity equation and mass-conservation calculations. 1 kg/s = 3 600 kg/h ≈ 2.205 lb/s.
