About Kilograms per hour
The kilogram per hour (kg/h) equals 1/3600 kg/s ≈ 2.778×10⁻⁴ kg/s, the dominant metric unit in the chemical and petrochemical industry for equipment sizing. Distillation column feed rates, reactor throughputs, heat-exchanger duty calculations, and pump datasheets routinely use kg/h. A 500 MW coal-fired power station burns ≈180 000 kg/h of coal. 1 kg/h ≈ 2.778×10⁻⁴ kg/s = 2.205 lb/h.
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.
